Information on Web Applications: ?
Introduction
Web application is an application delivered to users from a web server over a network such as the World Wide Web or an intranet. Web applications are popular due to the ubiquity of the web browser as a client, sometimes called a thin client. The ability to update and maintain web applications without distributing and installing software on potentially thousands of client computers is a key reason for their popularity. Web applications are used to implement webmail, online retail sales, online auctions, wikis, discussion boards, weblogs.
Application
Web interfaces have increasingly been used for applications that have previously been thought of as traditional, single-user applications. For example, Microsoft HTML Help replaced Windows Help as the primary help system in Microsoft Windows. Like their networked brethren, such applications generate web pages as their user interface and send them (sometimes via an embedded HTTP server) to a local web browser component, which then renders the pages for the user and returns user input to the application. Web applications powered by embedded web servers have also become commonplace as the user interfaces for configuring network components such as servers, routers, and gateways.
Writting Web Applications
While many web applications are written directly in PHP or mod_perl, there are many web application frameworks which automate the process, by allowing the programmer to define a higher-level description of the program.
