automated client billing, end user customization features, and multiple deployment options

including HTML/JavaScript, WAP, Pocket IE, and a Java based client.

Flooz.com: Created a RESTful URI based query language for SQL databases using JDBC. The

system takes a hierarchical view of an SQL database and querys it in a manner similar to

XPATH statements. It then returns the data found as an RDF or simpler XML document and

allows generic updating/deletion/insertion of data. It is used within Session Beans

deployed using WebSphere. In combination with XSL and CSS styling, a web based SQL

browser/editor was also created and used.

files and a MySQL database. It allows for user customization on the web site.

highly interactive game based community web site. The system was designed as a series of
