Database components include DBPrism components such as XML toolkits and applications code.
Java XML Toolkit (Jxtp) helps developer to generate XML tags using a serialized way, also support XML generation through DOM and Oracle's XML SQL Utility (XSU). This toolkit could be optimized into Oracle database compiled in a native form (ncomp).
PLSQL toolkit (xtp) is a toolkit built on top of Oracle's htp toolkit and provides a simple sets of procedures and functions to generate XML tags using htp like syntax (Html Toolkit Procedures is a group of related procedures or functions written in PLSQL for the Oracle 9iAS mod_plsql).
Toolkits regularly reside into sys or system database schemas.
Application packages include user developed applications such as the CMS, this application code resides into database user schemas and uses DBPrism toolkits through database synonyms.
Also a user could develop this own toolkit such as the XForms toolkit included into DBPrism CMS which generated W3C XForms tags using Jxtp toolkit.
