What is Web Application Development?
Web application development is the creation and maintenance of software applications to be used on the World Wide Web - Internet. It is performed by specialized programmers, who are familiar with the coding necessary for the creation of Web pages, including HTML, XML, Flash, Perl, CSS, PHP, JSP, ASP, and others. Each of these has a specific function and creates varied results. Web programmers must be proficient in one or more of these languages to some degree. Development can be varied or specific, depending on the needs of the Web pages involved.
One factor of Web application development that may not be evident to the casual observer is the number of revisions that such applications routinely involve. The World Wide Web is not a strictly controlled environment. People typically use the Web through only one or more of a large handful of methods, primarily Internet browsers. Each Web browser is slightly different and shows pages in slightly different ways. Some are friendlier to certain Web languages than others, and so programming for the Internet can be quite specialized. In a nut shell a web application development is simply a software delivered and used over the internet.
