PHP

Hypertext Preprocessor (PHP) is an open source server side programming language extensively used for web scripts and to process data passed via the Common Gateway Interface from HTML forms etc. PHP can be written as scripts that reside on the server and may produce HTML output that downloads to the web browser. Alternatively, PHP can be embedded within HTML pages that are then saved with a .php file extension. The PHP sections of the page are then parsed by the PHP engine on the server and the PHP code stripped out before the page is downloaded to the web browser. It is used for connecting to a database to create all kinds of web applications, such as product catalogs, changing content, calendars, and e commerce

MySQL

MySQL is a relational database management system, which means it stores data in separate tables rather than putting all the data in one big area. This adds flexibility, as well as speed. The SQL part of MySQL stands for "Structured Query Language," which is the most common language used to access databases. The MySQL database server is the most popular open source database in the world. It is extremely fast and easy to customize, due to its architecture. Extensive reuse of code within the software, along with a minimalist approach to producing features with lots of functionality, gives MySQL unmatched speed, compactness, stability, and ease of deployment. Their unique separation of the core server from the storage engine makes it possible to run with very strict control, or with ultra fast disk access, whichever is more appropriate for the situation.

Web Standards 2.0

Web Standards refer to standards for creating web sites that are internationally agreed on as the best practices. The World Wide Web Consortium (W3C), is the international governing body that oversees the development of web standards such as XHTML and CSS. Sites built to meet current web standards will be more accessible and more usable. Web Standards refer to standards for creating web sites that are internationally agreed on as the best practices.

AJAX

Asynchronous JavaScript And XML, or its acronym, Ajax is a Web development technique for creating interactive web applications. The intent is to make web pages feel more responsive by exchanging small amounts of data with the server behind the scenes, so that the entire Web page does not have to be reloaded each time the user makes a change. This is meant to increase the Web page's interactivity, speed, and usability
