Web application is website that contains pages stored on a web server with partly or entirely undetermined content. The final content page is determined only when the user requests a page from the server. Because the final content of the pages varies from request to request based from web server.
A regular website comprises a set of related HTML pages and files hosted in a computer running a web server. Web server is software that serves web pages in response to requests from web browsers. A page request is generated when a user clicks a link on a web page, chooses a bookmark in a browser, or enters URL in a browser’s Address text box and click Go.
When a web sever receives a request fro a regular web page, the server sends the page to the requesting browser. But, the server reacts differently when it receives a request for dynamic pages.
An application database serves to work with server-side resources such as database. For example, a dynamic page may instruct the application server to extract data from a database and insert it into the page’s HTML.
Planning is the most developed for web application in internet for create website. We would encounter numerous problems regarding the site at the time of publishing and at the time of accessing, if we made a site without planning.
