The information used by DB Test Driven framework and its components is stored in special tables known as framework tables.

Framework tables should not be altered directly by any user. For example, do not modify framework tables with DELETE, UPDATE, or INSERT statements, or user-defined triggers.

Reference of documented columns in framework tables are permissible. However, many of the columns in framework tables are not documented. Applications should not be written to query undocumented columns directly.

The format of the framework tables is dependent upon the internal architecture of DB Test Driven framework and may change from release to release. For that reason, applications that directly access the undocumented functionality may have to be changed before they can run in later version of DB Test Driven framework.
