Web application development

Web application development 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. To varying degrees, programmers are proficient in one or more of these languages. Web application 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 surf the Web using only one or a few of a large handful of methods, primarily browsers. Each Web browser is slightly different and shows Web pages in slightly different ways. Some are friendlier to certain Web languages than others, and so Web application development can be quite specialized.

Ajax Development

Ajax Development is a method of building interactive applications for the Web that process user requests immediately. Ajax combines several programming tools including JavaScript, dynamic HTML (DHTML), Extensible Markup Language (XML), cascading style sheets (CSS), the Document Object Model (DOM), and the Microsoft object, XMLHttp etc.Ajax allows content on Web pages to update immediately when a user performs an action, unlike an HTTP request, during which users must wait for a whole new page to load.
Ajax Development is not a proprietary technology or a packaged product. Web developers have been using JavaScript and XML in combination for several years. Ajax as a shorthand way to refer to the specific technologies involved in a current approach.
