What is a Web Application?
Web application is a software application that is accessed with a web browser over a network such as the Internet or an intranet. Web applications are popular due to the ubiquity of the 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, discussion boards, web bogs, online forums etc.
Structure of Web Application
A web application is commonly structured as a three-tiered application. In its most common form, a web browser is the first tier, an engine using some dynamic web content technology (e.g., CGI, PHP, Java Servlets or Active Server Pages) is the middle tier, and a database is the third tier. The web browser sends requests to the middle tier, which services them by making queries and updates against the database and generating a user interface.
A significant advantage of building web applications to support standard browser features is that they should perform as specified regardless of the operating system or OS version installed on a given client. Rather than creating clients for Windows, Mac OS X, GNU/Linux, and other operating systems, the application can be written once and deployed almost anywhere. However, inconsistent implementations of the HTML, CSS, DOM and other browser specifications can cause problems in web application development and support.
Depending on the type of application, it may require the development of an entirely different browser-based interface, or merely adapting an existing application to use different presentation technology.
Benefits of Web Applications
No special configuration
No special configuration or changes are need on users PCs. Everybody has a browser. This can lead to lower costs for browser-based software.
Data is centralized, secure and easy to backup, eliminating the need to synchronize data between locations.
Web applications are easy to change, and maintain. Updates can be made quickly and easily.
Biggest advantage of the web application, users have access from anywhere in the world, 24 hours a day, 7 days a week. Employees or agents located at different locations, on the road or even overseas, all have direct access to current information.
A web application can integrate data from existing systems.
A web based documentation or information center eliminates costly and wasteful distribution of printed materials and is always up-to-date, it can eliminate expensive multi-site licenses and above all No hardware upgrade is required for accessing the web-based applications
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, switches, routers, and gateways.
