What is the need for web applications?
Web applications have many uses for site visitors and developers, including the following.
Allows visitors to search for information quickly and easily to rich content sites:
This type of web application gives visitors the ability to search, organize, and navigate in the way they see fit. Examples include corporate intranets, Microsoft MSDN, and Amazon.com
The collection, archiving and analysis of data provided by visitors:
In the past, data entered in HTML forms were sent as e-mail messages to employees or CGI applications for processing. The web application can save form data directly into a database, extract data and generate web-based reports to be analyzed. Examples include online banking pages, retail sales pages, surveys, and user feedback templates.
Allows updating websites with constantly changing content:
Web applications on the web designer are having trouble updating the site's HTML content. Content providers, such as news editors, provide the web application with content, and the web application updates the site automatically.
