Web Application Development is the process of developing web application. A web application is an application that is accessed with the help of web browser over the internet. It is a computer software application that is coded in browser supported languages such as HTML, J2EE etc. The ability to update and maintain web applications without distributing and installing software on thousands of client computers is a main reason for the popularity of web applications. Common web applications include web mail, online retail sales, online auctions and many other functions.

In many entities there is requirement for applications on the internet. A good example would be Business-to-Business interaction. Many companies in the world today wanted to do business mutually over secure and private networks. This process is becoming popular. Applications of a website have a wide range from the simple process of transferring funds into a bank account to deploying a large scale Web services network that updates pricing information globally. Use of a Web applications infrastructure is beneficial for many businesses.
Based on the type of application, requirement may be to develop an entirely different browser-based interface or adapting an existing application in order to enable it to use different presentation technology. These programs allow the user to pay a monthly or yearly fee for use of a software application without having to install it on a local hard drive. A company which follows this strategy is known as an application service provider (ASP). Browser applications typically require little or no disk space on the client, upgrade automatically with new features, integrate easily into other web procedures, such as email and searching. They also provide cross-platform compatibility (i.e., Windows, Mac, Linux, etc.) because they operate within a web browser window. Browser software application solves problems in new ways that were not possible before, by using the power of your intranet or website. Your aim should be to take your organisation forward which can be made possible by removing the shackles of outdated systems.
