Get Married. Be Happy.
Matrimonial web sites are gaining popularity among young men, women and their parents. A big attraction for them is cost effectiveness of this idea.
Gone are the days when harried parents of the marriageable daughters waited for marriage brokers to come up with proposals from prospective bridegrooms who could match their choice and pockets. The scene was almost the same in the homes of bachelors; with the only difference that their parents were less harassed and less worried about money.
Now, things have changed quite a lot. The education of women has brought with it the power of independence. The Indian society has come a long way. There has been a drastic change in the attitude of both parents and their daughters. Women nowadays exercise their veto more often while choosing their bridegrooms. The situation for the boys too has improved; though even earlier their conditions were better off than the girls. One thing that has become clear and loud with the change is that today the Indian marriage is increasingly becoming a union of two individuals rather being a union of two families.
Marriages in India are categorized mainly under two types: love marriage and arranged marriage. Love marriage is getting full-fledged support from our own dear dream weaver, the one and only Bollywood.
Things now have come a long way. It is not that the earlier two forms do not exist any more, but there has been a perceptible change in the outlook of the educated middle and the upper middle class. The classifieds of the renowned English and the vernacular dailies now have taken place of the marriage brokers. But, the ones who are creating ripples in the business of finding the right match are the matrimonial sites. Shaadi.com, Jeevansaathi.com, 123India.com Matrimonials, BharatMatrimony.com, etc. are some of the popular matrimonial web sites.
Just a click of the mouse, and a whole world of information about men and women of marriageable age unravel in front of the user. These sites provide free registrations for their users and also help them in creating attractive looking profiles. The sites enable their user to search matches, that meet their respective criteria and can even email or chat with the registered members. The site does not only help the prospective brides and bridegrooms but are helpful for their parents also.
The choice is extensive for the netizens, who are hooked on to these sites. The user can avail many search options. The member just has to mention about the desired community or the desired job profile or the choice of the country or city for the match search. There are options for selecting the desired complexion and height in these matrimonial web sites. Some sites are exclusively for the Non-Resident Indians (NRIs). India Canada Marriage is one such web site for Indo-Canadians. India Matches is another matrimonial web site where one can search for a life partner or find a date or meet a friend through the Internet.
The matrimonial sites do not restrict themselves to the role of an information provider of the ready-to-be brides and the bridegrooms. They are just ready with all kinds of information associated with marriage starting from the information about designers, renowned shops of trousseau, to even decorators, florists, caterers and wedding halls. Now, the question that may come to everybody's mind is that whether people are really benefited by it or not. The success stories that have been put up on these sites assert that the people do get benefits. But, there is also another side of the story. Many young men and women log on to these sites just for chatting and dating on the net. In many offices, guys are often seen these sites regularly just to see the pictures of the girls, to take their email addresses, to chat and to meet them later on to be browsing through.

DISADVANTAGES
1. Poor communication between users.
2. Photo size is small.
CHAPTER 2 SOFTWARE DEVELOPMENT LIFE CYCLE
The prime objective of the system is to develop a application for satisfying all requirements of the client and it should be capable of handling large volume of customers. The overall system must be fast and convenient. The classical System Development life Cycle (SDLC) method, the Prototype model has been used here. It is the most widely used paradigm for system development. This process demands a systematic, sequential approach to software development. The life cycle involves the following activities:
2.1 SYSTEM ANALYSIS
2.1.1 System study
System studies results in finding out details of the existing methodologies that are being followed and that whether any developments is to be made. These studies considered both the existing and the proposed system.
System study had been conducted to analyze the current existing system of matrimonial websites. All the current websites have been analyzed
2.1.2 Existing system
In the existing system the advertisement and marriage is done through newspapers and marriage beauro. So the current system is an old one in this computer world and it has many drawbacks. The main problem is regarding time as well as cost. The cost of advertisement and searching of the partners through newspapers and consultancy are difficult.
In the manual system we waist the time. Later it leads to confusion and lack of knowledge of the bride and grooms.. As paper advertisement involved in the manual maintenance is high, keeping of unnecessary data, leading piles of waster paper.
In this fast changing world, in each and every home there is a computer with net connection. So the present system has become an easy, fast, and cost effective way of through mails.

2.3 SYSTEM DESIGN
The importance of software design can be found with a single word, quality. Designing is the phase in which quality is fastened in a software development. Design is the only way that can accurately translate the Customer's requirements into a finished software product. A system, which is not properly designed, may fail when small changes are made. Thus, the primary objective of design phase is to determine how the system has to be developed. System design is a process that identifies inputs, outputs and explains functions of the system. This important phase is composed of several steps. It provides understanding of the procedural details, necessary for implementing. Emphasis has been given for translating the performance requirements. Understanding the data flow and the database that is to be designed forms an important aspect of the designing process. Generally System Design includes the following types:
2.3.1 Logical Design
Logical design describes the format of inputs, outputs, and procedures that meets the user requirements.
The design covers the following:
> Reviews the current physical system.
> Prepares the output specification.
> Prepares the Input specifications.
> Prepares controls specifications.
2.3.2 Physical Design
This produces the working system by defining the design specifications that tell the programmers exactly what the system must do. The programmers write the necessary programs that accept inputs from the user, perform the necessary calculations, produce hardcopy of the report or display it on the screen Design the Physical system.
> Specify the Input/Output media.
> Design physical information flow through the system.
> Plan system implementation.
The flow of data through out the project was graphically represented using DFD so that the internal flow of process can be easily understood. If design is performed in a detailed manner, then coding can be done mechanically.
2.4 SYSTEM IMPLEMENTATION
This is the stage of the project when the theoretical design is tuned into a working system. If the implementation stage is not carefully controlled and planned, it can cause chaos. Thus it can be considered to be the most critical stage in achieving a successful new system and in giving the users a confidence that the system will work and be effective.
The implementation stage in a project has its own right. It involves
> Careful planning
> Investigation of the current system and the constraints on implementation.
After the successful completion of the design phase, the next important step is the development of the system according to the specified design. The main procedure of this phase is coding of the deigned system, in order to satisfy the requirements. The detailed input/output, text manipulation, logic comparison and storage/retrieval operations during the system analysis stage provide input for the program preparation. Coding was carried out in a step-by-step manner. One or more programmers convert these operations into a program of instructions written in a language and form acceptable to the computer hardware. In our project user inter-activeness was given stress and the system gives maximum flexibility. Proper validations were done for every user-defined function.
The principal activities performed during the development phase can be divided into two major related sequences. These are
1. External system development
2. Internal system development
The primary external system development activities include Implementation planning. The principal internal system development activities are computer program development and performance.
2.5 SYSTEM TESTING
No system design is ever perfect. Communication problems, programmer's negligence, or time constraints create errors that must be eliminated before the system is ready for user acceptance testing. A system is tested for online response, volume of transactions, stress, recovery from failure and usability. Then comes system testing, which verifies that the whole test of programs hangs together following system testing is acceptance testing, or running the system with live data by the actual user.
2.5.1 Static Testing Purpose
Code should be reviewed where necessary to ensure it follows project coding and design standards. Code reviews are not meant to check program logic. Adherence to acceptable programming standards is crucial for future maintenance. These will change over time as technology develops.
2.5.2 Dynamic Testing
The traditional 'prototype' lifecycle breaks dynamic testing down into a number of phases such as unit, integration, system and acceptance testing. Whatever methodology is being followed, a software system is typically organized into a number of units comprising a single logical function or several related functions needing access to shared data. It is sensible and efficient to test these 'units' as they are developed. Black box and white box testing may be used for this purpose:
Functional (black-box) Testing means testing that the 'unit' does what it is supposed to do, and does not do what it is not supposed to do. This was tested in our Email Flyer both in unit wise and units altogether after integration. In other words, it is tested against its functional requirements, both positive and negative, as stated in the specification. This is known as black box testing, since it requires no knowledge of the inner workings of the unit.
Structural (white-box) Testing is concerned with the degree to which test cases exercise or 'cover' the logic of the program. The logic of the program was tested and checked whether it meet the requirements correctly.
2.5.3 Acceptance Testing
The need for acceptance testing will vary from project to project. It is worthwhile noting the purpose of acceptance testing. It is not supposed to be an unsupervised ad hoc activity undertaken by the client. It should be strictly controlled. For that reason there are a number of requirements, which are applicable if
acceptance testing proves necessary. The project manager should select these from the following that are applicable for a particular project.
Acceptance tests relate to the functionality of the system as stated in the requirements specification, and functional test cases must be selected to satisfy the agreed acceptance criteria. In the majority of cases, suitable test cases will exist among those used for system testing.
These tests cover areas such as performance, security, reliability, load/stress testing, volume testing, human computer interaction tests, configuration testing, compatibility testing, documentation, and human procedures. Sufficient tests must be devised to satisfy the agreed acceptance criteria.
Since acceptance tests in particular can make heavy demands on resources, and will have been performed as part of system testing, an alternative and equally acceptable procedure is to have the client witness a part of the system test. In that case client witnessed system testing must conform to the requirements for acceptance testing with respect to procedure, conduct, and documentation. It is recommended that this approach is adopted wherever possible as it ensures that testing is performed under carefully controlled conditions.
2.6 TEST PROCEDURES AND TEST REPORTS
The acceptance test procedures must be documented. The acceptance test procedure should specify the steps to be taken in carrying out the tests, and for formal acceptance tests needs to be rigorous, complete and unambiguous.
The acceptance test procedure specification must be subject to review prior to the dry run. The results of both the dry run and the acceptance tests must be documented. A test log and any test observation reports should be completed as the tests are conducted. A test summary review should be completed as soon after completion of the tests as possible.
2.7 MAINTENANCE
Software will undoubtedly undergo changes after it has been delivered to the user. Change will occur because errors have been encountered, because the software must be adapted to accommodate changes in external environment or because the user requires functional or personal enhancements. Software maintenance reapplies each of the preceding life cycle steps to an existing program rather than a new one.
The basic idea of the SDLC method is that there is well-defined process by which the application is conceived, developed and implemented. It gives the structure to a creative process. The phases in the SDLC provides a basis for management and control because they define segments of flow of work which can be identified for management purpose and specify the documents or other deliverables to be procured in each phase.
A thorough analysis of the existing system is done and the new requirements for the proposed system are studied. The entire application is modularized considering the features required for the proposed system.
CHAPTER 3 TOOLS
3.1 INTRODUCTION TO PHP
PHP is a powerful language and the interpreter, whether included in a web server as a module or executed as a separate CGI binary, is able to access files, execute commands and open network connections on the server. These properties make anything run on a web server insecure by default. PHP is designed specifically to be amore secure language for writing CGI programs than Perl or c, and with correct selection of compile-time and runtime configuration options, and proper coding practices, it can give you exactly the combination of freedom and security you need.
As there are many different ways to utilizing PHP, there are many configuration options controlling its behavior. A large selection of options guarantees you can use PHP for a lot of purpose, but it also means there are combination of these options and server combinations that result in an insecure setup.
The configuration flexibility of PHP is equally reveled by the code flexibility .PHP can built complete server applications, with all the power of shell user or it can be used for simple server- side includes with little risk in a tightly controlled environment. how you build that environments, and how secure it is largely up to the PHP developer.
This chapter starts with some general security advice, explains the different configuration option combinations and the situations they can be safely used and describes different considerations in coding for different level of security.
3.1.1 What Is PHP
PHP (recursive acronym for "PHP: Hypertext Preprocessor") is a widely used open source general purpose scripting language that is especially suited for Web development and can be embedded in to HTML.
Notice how this is different from a script written in other languages like Perl or c instead of writing a program with lots of commands to output HTML, you write an HTML script with some embedded code to do something (in this case, output some text). The PHP code is enclosed in special start and end tags that allow you to jump in to and out of'PHP mode"
What distinguishes PHP from something like client-side JavaScript is that the code is executed on the server. If you were to have a script similar to above on the server, the client would receive the result of running that script, with no way of determining what they underlying code may be. You can even configure your web server to process all your HTML files with PHP, and then there's really no way that users can tell what you have up your sleeve.
The best things in using PHP are that it is extremely simple for a newcomer, but offers many advanced features for a professional programmer. Dont be afraid reading the long list of PHP's features. You can jump in a short time, and start writing simple scripts in a few hours.
General Installation considerations
Before starting the installation, first you need to know what do you want to use PHP for. There are three main fields you can use PHP
Server-side scripting
Command line scripting
Client-side GUI applications
For the first and most common form, you need three things: PHP itself, a web server and a web browser. You probably already have a web browser, and depending on your operating system setup, you may also have a web server (e.g. Apache on Linux and MacOS X;IIS on Windows). You may also rent web space at accompany. This way, you don't set up anything on your own, only write your PHP scripts, upload it to the server you rent, and see the results in your browser.
While setting up the server and PHP on your own, you have two choices for the method of connecting PHP to the server. For many servers PHP has a direct module interface (also called SAPI). These servers include Apache, Microsoft Internet Information Server, Netscape and iPlanet servers. Many other servers have support for ISAPI, the Microsoft module interface (Omni HTTP for example). If PHP has no module support for your web server, you can always use it as a CGI or Fast CGI processor. This means you setup your server to use the CGI executable of PHP to process all PHP file requests on the server.
If you are also interested to use PHP for command line scripting (e.g. write scripts auto generating some images for you offline, or processing text files depending on some arguments you pass to them), you always need the command line executable.
With PHP you can also write to the desktop GUI application using the PHP-GTK extension. This is a completely different approach than writing the pages, as you do not output any HTML, but manage windows and objects within them.
3.1.2 Error Reporting
With PHP security, there are two sides to error reporting. One is beneficial to increasing security, the other is detrimental.
A standard attack tactic involves profiling system by feeding it improper data, and checking for the kinds, and context, of the errors, which are return. This allows the system cracker to probe for information about the server, to determine possible weaknesses. For e.g. If an attacker an had gleaned information about a page based on prior form submission, they may attempt to override variables, or modify them:
The PHP errors normally return can be quite helpful to a developer who is trying to debug a script, indicating such things as the function or file that failed the PHP file it failed in, and the line number that occurred in. This is all information that can be exploited. it is not uncommon for a PHP developer to use show source() ,highlight string(),or highlight files() as a debugging measure, but in a live site , this can be expose hidden variables, unchecked syntax ,and other dangerous information. Especially dangerous is running code from non-sources with built-in debugging handlers or using common debugging technique. If the attacker can determine what general technique you are using, they may try to brute-force a page, by sending various common debugging strings:
Regardless of the method of error handling, the ability to probe a system for error leads to providing attacker with more information.
For example, the very style of a generic PHP error indicates system is running PHP.If the attacker was looking at an .html page, and wanted probe for the back-end (To look for known weakness in the system), by feeding it the wrong data they may be able to determine that a system pass built with PHP.
A function error can indicate whether a system may be running a specific database engine, or give clues as to how a web page or programmed or designed. This allows for deeper investigation into open database ports, or to look for specific bugs or weakness in a web page. By feeding different pieces or bad data, for example, an attacker can determine the order of authentication in a script, (from the line number errors) as well as probe for exploits that may be exploited in different locations in the scripts.
A file system or general PHP error can indicate what permissions the webserver has, as well as the structure and organization of files on the web server. Developer written error code can aggravate this problem, leading to easy exploitation of formerly "hidden" information.
There are three major solutions to this issue. The first is to scrutinize all functions, and attempt to compensate for the bulk of the errors. The third is to use PHP's custom error handling functions to create your own error handler. Depending on your security policy, you may find all three to be applicable to your situation.
One way of catching this issue ahead of time is to make use of PHP's own error reporting (), to help you secure your code and find variable usage that may be dangerous. By testing your code, prior to deployment, with EALL, you can quickly find you area where your variables may be open to poisoning or modification in other ways. Once you are ready for deployment, you should either disable error reporting completely by setting error reporting () to 0, or turn off the error display using the php.ini option display_ errors, to insulate your code from probing. If you choose to do the latter, you should also define the path to your log file using the error log in directive, and turn log error on.
3.1.3 Connecting to Database
You may want to establish the connection over SSL to encrypt client/server communications for increased security, or you can use the database server. If either of these is used, then monitoring your traffic and gaining information about your database will be difficult for a would-be attacker.
3.1.4 Encrypt Storage Model
SSL/SSH protects data traveling from the client to the server SSL/SSH does not protect the persistent data stored in a database. SSL is an on-the-wire protocol.
Once an attacker gains access to your database directly (bypassing the web server), the stored sensitive may be exposed or misused, unless the information is protected by the database itself. Encrypting the data is a good way to mitigate this threat, but very few databases offer this type of data encryption.
The easiest way to work around this problem is to first create your encryption package, and then use it from within your PHP scripts.PHP can assist you in this with several extentions,such as Mcrypt and Mhash covering a wide variety of encryption algorithms. The script encrypts the data before inserting it in to the database, and decrypts it when retrieving. See the reference for further examples of how encryption works.
In case of truly hidden data, if its raw representation is not needed (i.e. not be displayed), hashing may also be taken in to consideration. The well-known example for the hashing is storing the MD5 hash of a password in a database, instead of password itself.
3.1.5 Hiding PHP
In general security by obscurity is one of the weakest forms of security. But in some cases, every little bit of extra security is desirable.
A few simple techniques can help to hide PHP, possibly slowing down an attacker who is attempting to discover weakness in your system. By setting expose_php=off in your php.ini file, you reduce the amount of information available to them.
Another tactic is to configure is to configure web servers such as apache to parse different file types through PHP, either with a hatches directive, or in the apache configuration file itself. You can then use misleading file extensions:
3.2 HTTP AUTHENTICATION WITH PHP
The HTTP Authentication hooks in PHP are only available when it is running as an Apache module and is hence not available in the CGI version .In an Apache module PHP script, it is possible to use the header () function to send an "Authentication Required " message to the client browser causing it to pop up a Username /Password input window. Once the user has filled in a username and password, the URL containing the PHP script will be called again with the predefined variables_PHP_AUTH_USER, PHP_AUTH_PW, and AUTH_TYPE set to the username, password and authentication type respectively. These predefined variables are found in the $SERVER and $HTTP_SERVER_VARS arrays. Only "Basic" authentication is supported.
3.2.1 Cookies
PHP transparently supports HTTP cookies. Cookies are a mechanism for storing data in the remote browser and thus tracking or identifying return users. You can set cookies using the set cookie or set raw cookie () function. Cookies are part of the HTTP header; so set cookie () must be called before any output is sent to the browser. This is the same limitation that header () has. You can use the output buffering functions to delay the script output until you have decided whether or not to set any cookies or sent any headers.
Any cookies sent to you from the client will automatically be turned in to a PHP variable just like GET and POST method data, depending on the register global and variables order configuration variables .If you wish to assign multiple values to a single cookie, just add [] to the cookie name.
In PHP 4.1.0and later, the $_COOKIE auto global array will always be sent with any cookies sent from the client.
$HTTP_COOKIE_VARS is also set in earlier versions of PHP when the track vars configuration variable is set
3.2.2 Sessions
Session supports in PHP consist of a way to preserve certain data across subsequent accesses. This enables you to build more customized applications and increase the appeal of your web site. The session module cannot guarantee that the information you store in a session .You need to take additional measure to actively protect the integrity of the session, depending on the value associated with it.
Assess the importance of the data carried by your sessions and deploy additional protections _this usually comes at a price, reduced convenience for the user. For example, if you want to protect users from simple social engg: tactics, you need to enable session. Use _only _cookies. In that case, cookies must be enabled unconditionally on the user side, or sessions will not work.
There are several ways to leak an existing session id to third parties. A leaked session id enables the third party to access all resources, which are associated with a specific id. First URLs caring session ides' you page link to an external site, the URL including the session id might be stored in the external sites referrer logs. Seacond,a more attacker might listen to your network traffic .If it is not encrypted ,session ids will flow in plain text or the network the solution here is to implement SSL on your server and make it mandatory for users .
Optionally you can use shared memory allocation (mm) developed by Ralf S.englehall for session storage you have to download mm and install it. This option is not available to windows platforms .not that the session storage module for mm does not guaranty that concurrent access to the same session is properly locked.
3.2.3 Installation
Session support is enable in PHP by default if you would not like to build your PHP with session support you should specify the disable session options to configure to use shared memory allocation (mm) for session storage configure PHP -with-mm [=DIR].
The windows version of PHP has built in support for this extension you do not need to load any additional extension in order use this functions.
BY default all data related to particular session will be stored in file in the directory specified by the session. Save path INI option. File for each session (regardless if any data if associated with that session) will be created. This is due to the fact that session is opened (file is created) but no data is even return to that file not that these behavior is aside effect of limitation of working with the file system and it is possible that accustom session handler (such as one which uses database) does not keep track of session which store no data
3.2.4 PHP vs. .ASP?
ASP is no really a language in itself, it's an aroma for active server pages the actual language is used to program asp with is Visual Basic Script or Jscript.The biggest draw of ASP is that a it's a proprietary system that is natively used on Microsoft internet information server (IIS). This limit it's availability to win 32-based servers there are a couple of projects in the works that allows ASP to run in other environments and webservers. InstantASP from Halcyon (commercial) chily! Soft ASP from chily! Soft (commercial) ASP is said to be slower and comp some language than script it's
Relatively easy to pick up the language you already know how to program in Visual Basic. ASP support is also enabled by default in the IIS server making it easy to get up and running. The components built in ASP are really limited, so if you need to use" advanced" features like interacting with FTP servers you need to buy additional components.
PHP is commonly said to be faster and more efficient for complex programming tasks and trying out new ideas. PHP generally referred to as more stable and less resource intensive as well. Cold Fusion has better error handling, database abstraction and date parsing although database abstraction is addressed in PHP 4.Another thing that is listed as one of Cold Fusion's strength is its excellent search engine, but it has been mentioned that a search engine is not something should be included in a web scripting language .PHP runs on almost every platform there is Cold Fusion is only available on Win 32,Solaris, Linux and HP/UX.Cold Fusion has a good IDE and Is generally easier to get started with where as PHP initially requires more programming knowledge. Cold Fusion is designed with nonprogrammers in mind while PHP is focused on programmers
3.2.5 PHP vs. Perl
The biggest advantage of PHP over perl is that PHP was designed for scripting for the web where Perl was designed to do a lot more and can because of these get very complicated the flexibility or complexity of Perl makes it easier to write code that another author or coder has a hard time reading PHP was a less confusing and stricter format without losing flexibility. PHP is easier to integrate in to existing HTML than
Perl PHP
has pretty much all the" good" functionality of Perl constructs, syntax and so on ,without making it as complicated as Perl can be.Perl is very tried and true language its been around since late eighties but PHP is maturing very quickly.
3.3 ABOUT MYSQL
3.3.1 Introduction
PHP and MySQL, two make up what must be the best combination for data-driven Web sites on the planet. You needn't take my word for it. An unofficial Netcraft survey shows that PHP usage has jumped from 7,500 hosts in June 1998 to 410,000 in March 1999.That's not bad. The combination was also awarded Database of the year at Webcon98, where it received a lovely tiara.
MySQL is a small, compact database server ideal for small - and not so small - applications. In addition to supporting standard SQL (ANSI), it compiles on a number of platforms and has multithreading abilities on Unix servers, which make for great performance. For non-Unix people, MySQL can be run as a service on Windows NT and as a normal process in Windows 95/98 machines.
In addition to being free (My SQL does have some licensing restrictions though), the PHP- MySQL combination is also cross-platform, which means you can develop in Windows and serve on a Unix platform. Also, PHP can be run as an external CGI process, a stand-alone script interpreter, or an embedded Apache module.
3.3.2 Installing MySQL
MySQL central is http://mysql._As befits a program of its stature, there are a zillion mirrors located all over the globe, so do the internet a favor and pick the one closet to you.
You've got plenty of choices at this point. If you're a do-it yourselfer, then grab the source code. If you're not that brave, there are some precompiled binaries for other platforms already available for download.
In addition, there is a shareware version of MySQL for windows users. It is an older version of MySQL. If you want the latest version, you'll have to purchase a license. There are also ODBC drivers that let your applications talk to MySQL.Various other exciting bits and pieces are lurking about on the site, too, so take a look.
The precompiled Unix versions and the Windows version are as simple as unpacking and going, and they don't require much explanation. So let's compile from the source code. Windows users, please keep in mind that you need to run MYSQL in the mysql/bin directory.
MySQL comes with a handy configuration script. Simply type. /configure and let things take care of them. If you need to specify what happens and where, typing. /configure help gives you a list of options to choose from. For example, if you're compiling on a machine with little memory, you can opt for the -with-low-memory flag. I like MySQL to install in one handy directory tree rather than in various locations on my machine, so I specify an install location with the -prefix flag.
You can also specify lots of other options, such as what to compile and what to skip. Let's assume that we want everything under /user/local/mysql on our server. This means we'd type. /configure -prefix=/user/local/mysql.
The configure script will run and inspect your system and then build the necessary files to successfully compile. If it fails, you'll usually get a helpful error message saying why. Quite often, you'll find the script will fail when it's looking for threading libraries. Check that you've got MIT-pthreads installed on your machine, and if not, add them. Linux users will have to download Linux Threads.
These are critical libraries that allow MySQL to multithread (i.e. run multiple versions of itself). Recent distributions of Linux may already have these libraries installed.
If everything goes according to plan, simply type make and go get a coffee. MySQL is a complex program and takes some time to compile. If you get an error, check the documentation to see if there is anything specific that you've missed for your particular OS.
Next, type makes install and all the necessary files will be installed in all the necessary spots. Now you're almost ready to roll! If you are a MySQL virgin and you've never installed MySQL before, you need to create the default permissions, so type.. scripts/mysql_install_db to set these up.
3.3.3 Simple Validation
Imagine for a moment that we've got our database nicely laid out and we're now requesting information from users that will be inserted into the database. Further, let's imagine that you have a field in your database waiting for some numeric input, such as a price. Finally, imagine your application falling over in a screaming heap because some smart aleck put text in that field. MySQL doesn't want to see text in that portion of your SQL statement- and it complains bitterly.
Validation simply means that we'll examine a piece of data, usually from an HTML form, and check to make sure that it fits a certain model. This can range from ensuring that an element is not blank to validating that an element meets certain criteria (for example, that a numeric value is stipulated or that an email address contains an @ for an email address).
Validation can be done on the server side or on the client side. PHP is used for server-side validation, while JavaScript or another client-based scripting language can provide client-side validation. This article is about PHP, so we're going to concentrate on the server end of things.
Let's ignore our database for the moment and concentrate on PHP validation. If you wish, you can add additional fields to our employee database quite simply by using the MySQL ALTER statement that is, if you want to commit to the values that we'lljvalidate.
There are several useful PHP functions we can use to validate our data and they range from simple to highly complex. a simple function we could use might be strlen (),which tells us the length of the variable.
A more complex function would be ereg (), which uses full regular expressionjiandling for complex queries. I wont delve in to the complexities of regex here, as entire books have been written on the subject, but I will provide some examples on the next page.
To select a value from the database we can use the following script inside PHP tags $sql="SELECT * from my table"; $result=db_query ($sql);
3.3.4 Conclusion
When it comes to databasing, there's lot to page learn. If you haven't done it already, find a good book about database design and learn to put together a slid database-on any platform. It's a complex but interesting database with a wealth of useful documentation. Learn about table structure, data types and SQL.You can actually achieve some pretty impressive stuff if you know enough SQL.
Finally there's PHP.web site has nearly everything you need, from a comprehensive manual to mailing list archives to code repositories. An excellent way to learn about PHP is to study the examples used in the manual and to check out the code archives. Manny of the posted scripts consist of functions or classes that you can use for free in your own scripts consist of functions or classes that you can use for free in your own scripts without having to reinvent the wheel. Additionally the mailing list is an excellent spot to check out if you get stuck. The developers themselves read the list and there are plenty of knowledge people there who can help you along the way.

Get Married. Be Happy.
Matrimonial web sites are gaining popularity among young men, women and their parents. A big attraction for them is cost effectiveness of this idea.
Gone are the days when harried parents of the marriageable daughters waited for marriage brokers to come up with proposals from prospective bridegrooms who could match their choice and pockets. The scene was almost the same in the homes of bachelors; with the only difference that their parents were less harassed and less worried about money.
Now, things have changed quite a lot. The education of women has brought with it the power of independence. The Indian society has come a long way. There has been a drastic change in the attitude of both parents and their daughters. Women nowadays exercise their veto more often while choosing their bridegrooms. The situation for the boys too has improved; though even earlier their conditions were better off than the girls. One thing that has become clear and loud with the change is that today the Indian marriage is increasingly becoming a union of two individuals rather being a union of two families.
Marriages in India are categorized mainly under two types: love marriage and arranged marriage. Love marriage is getting full-fledged support from our own dear dream weaver, the one and only Bollywood.
Things now have come a long way. It is not that the earlier two forms do not exist any more, but there has been a perceptible change in the outlook of the educated middle and the upper middle class. The classifieds of the renowned English and the vernacular dailies now have taken place of the marriage brokers. But, the ones who are creating ripples in the business of finding the right match are the matrimonial sites. Shaadi.com, Jeevansaathi.com, 123India.com Matrimonials, BharatMatrimony.com, etc. are some of the popular matrimonial web sites.
Just a click of the mouse, and a whole world of information about men and women of marriageable age unravel in front of the user. These sites provide free registrations for their users and also help them in creating attractive looking profiles. The sites enable their user to search matches, that meet their respective criteria and can even email or chat with the registered members. The site does not only help the prospective brides and bridegrooms but are helpful for their parents also.
The choice is extensive for the netizens, who are hooked on to these sites. The user can avail many search options. The member just has to mention about the desired community or the desired job profile or the choice of the country or city for the match search. There are options for selecting the desired complexion and height in these matrimonial web sites. Some sites are exclusively for the Non-Resident Indians (NRIs). India Canada Marriage is one such web site for Indo-Canadians. India Matches is another matrimonial web site where one can search for a life partner or find a date or meet a friend through the Internet.
The matrimonial sites do not restrict themselves to the role of an information provider of the ready-to-be brides and the bridegrooms. They are just ready with all kinds of information associated with marriage starting from the information about designers, renowned shops of trousseau, to even decorators, florists, caterers and wedding halls. Now, the question that may come to everybody's mind is that whether people are really benefited by it or not. The success stories that have been put up on these sites assert that the people do get benefits. But, there is also another side of the story. Many young men and women log on to these sites just for chatting and dating on the net. In many offices, guys are often seen these sites regularly just to see the pictures of the girls, to take their email addresses, to chat and to meet them later on to be browsing through.

DISADVANTAGES
1. Poor communication between users.
2. Photo size is small.
CHAPTER 2 SOFTWARE DEVELOPMENT LIFE CYCLE
The prime objective of the system is to develop a application for satisfying all requirements of the client and it should be capable of handling large volume of customers. The overall system must be fast and convenient. The classical System Development life Cycle (SDLC) method, the Prototype model has been used here. It is the most widely used paradigm for system development. This process demands a systematic, sequential approach to software development. The life cycle involves the following activities:
2.1 SYSTEM ANALYSIS
2.1.1 System study
System studies results in finding out details of the existing methodologies that are being followed and that whether any developments is to be made. These studies considered both the existing and the proposed system.
System study had been conducted to analyze the current existing system of matrimonial websites. All the current websites have been analyzed
2.1.2 Existing system
In the existing system the advertisement and marriage is done through newspapers and marriage beauro. So the current system is an old one in this computer world and it has many drawbacks. The main problem is regarding time as well as cost. The cost of advertisement and searching of the partners through newspapers and consultancy are difficult.
In the manual system we waist the time. Later it leads to confusion and lack of knowledge of the bride and grooms.. As paper advertisement involved in the manual maintenance is high, keeping of unnecessary data, leading piles of waster paper.
In this fast changing world, in each and every home there is a computer with net connection. So the present system has become an easy, fast, and cost effective way of through mails.

2.3 SYSTEM DESIGN
The importance of software design can be found with a single word, quality. Designing is the phase in which quality is fastened in a software development. Design is the only way that can accurately translate the Customer's requirements into a finished software product. A system, which is not properly designed, may fail when small changes are made. Thus, the primary objective of design phase is to determine how the system has to be developed. System design is a process that identifies inputs, outputs and explains functions of the system. This important phase is composed of several steps. It provides understanding of the procedural details, necessary for implementing. Emphasis has been given for translating the performance requirements. Understanding the data flow and the database that is to be designed forms an important aspect of the designing process. Generally System Design includes the following types:
2.3.1 Logical Design
Logical design describes the format of inputs, outputs, and procedures that meets the user requirements.
The design covers the following:
> Reviews the current physical system.
> Prepares the output specification.
> Prepares the Input specifications.
> Prepares controls specifications.
2.3.2 Physical Design
This produces the working system by defining the design specifications that tell the programmers exactly what the system must do. The programmers write the necessary programs that accept inputs from the user, perform the necessary calculations, produce hardcopy of the report or display it on the screen Design the Physical system.
> Specify the Input/Output media.
> Design physical information flow through the system.
> Plan system implementation.
The flow of data through out the project was graphically represented using DFD so that the internal flow of process can be easily understood. If design is performed in a detailed manner, then coding can be done mechanically.
2.4 SYSTEM IMPLEMENTATION
This is the stage of the project when the theoretical design is tuned into a working system. If the implementation stage is not carefully controlled and planned, it can cause chaos. Thus it can be considered to be the most critical stage in achieving a successful new system and in giving the users a co
