The main motivation to work like the PLSQL Cartridge of Oracle Web Server is to allow old technologies to coexist with new ones, helping in the migration path. Using DBPrism it is possible to run applications made to work with Oracle Web Server ( OWS ) in the same box or the latest Oracle Internet Application Server ( IAS ) mod_plsql without any modifications.
This kind of application includes applications designed with Oracle Designer - Web Server Generator or Oracle HTML DB , and standalone applications made using the PLSQL HTP toolkit (Html Toolkit Procedures is group of related procedures or functions written in PLSQL to make application for the Oracle Web Server architecture). For further information on how these applications work, refer to the developer's manuals of these products.

DBPrism already includes support for Oracle databases, but its design allows developers to write adapters to plug into many other kinds of databases.
