	Web sites are an incredibly important medium for making information available on the Internet. It is important to be able to have effective and maintainable web sites. Web sites can be simple static collections of pages, but for many, more complicated business requirements it may be necessary to develop complete web applications. Gethos helped develop core components for the VenueDirectory.com site. This is a live site that clearly demonstrates the power of web applications and uses technologies such as JavaScript, Java Servlets, XML, XSL to create the HTML viewed by the web browser. The data is stored in the PostgreSQL relational database. In addition to using Java to create dynamic web applications, there are other powerful tools such as PHP (similar to ASP) and CGI. PHP is an excellent web scripting language for rapidly developing web page content where the information needs to be dynamically updated, generated from database content or where users need to fill in forms so that the data can be processed on the server. The CGI mechanism was the forerunner to web scripting languages and the programs are written in languages such as Perl or C++. Although not often used, CGI programs still have some advantages of scripting languages and are thus useful in certain situations.
