Dynamic Web General Architecture
The challenge of integrating web server and database information
in a system environment has been solved by various technologies
with a similar architecture. In this architecture, traditional
HTML is intermixed with a programming language and script, and interpreted
by an engine (Dynamic Web Pages). While HTML, style sheets
and related scripts are responsible for the presentation of the
information, the programming language typically contains the logic
and connectivity code.
While ordinary
web pages (static web pages) are simply served by a Web server,
dynamic web pages are parsed through a separate engine that processes
backend programming code to execute the intended application.
The program results are then integrated back in an HTML page and
is sent out to the browser for display. Three popular technologies
that implement this architecture are Microsoft's Active Server Pages
(ASP), Allaire's Cold Fusion and Java Server Pages (JSP). The Dynamic
Web Application Systems provide the foundation for your application
and a standardized programming environment for your team.
