Every XML element type corresponds to a Python class, and these Python classes provide a conversion method to transform the XML tree (e.g. into HTML). XIST can be considered 'object-oriented XSLT'. XIST also includes a cross-platform templating language, Oracle utilities, and various other tools.

LightProfiler provides performance analysis of Oracle databases. It generates detailed resource profiles for extended SQL trace files, containing information about the consuming of response time (by events, by cursors, etc.), data file usage, error analysis (SQL, PL/SQL), and much more. It also contains tools for additional processing of trace files (extracting session data, splitting files) and for management of a database's sessions (disconnecting, tracing, monitoring parameters, blocking locks, events, etc.).
