A web application is any website that does
something useful, as opposed to simply informative websites or
brochure-ware. When a website provides a place for browsers to
enter their contact information, for example, and that information
is captured in a way that makes it usable at a later date, the
website is then technically
a web application.
practice, however, web applications tend to be a bit more robust,
and indeed their are some extremely powerful web applications out
there. MapQuest, for example, is a powerful tool for
downloading maps and driving directions to and from anywhere.
Yahoo provides dozens of powerful web applications for everything
from buying movie tickets to selling a car.
applications are generally server-side technologies, meaning that
the actual program and its execution run on the web server.
Typical server-side technologies include ASP, ASP.NET, PHP, JSP,
Cold Fusion and several others. Datasushi developers work

applications are almost always tied to a database of some kind,
running on the web server or other centralized location. This

host in Spokane, Washington, to generate the links below and their
