Database Schema Reference
This section provides an annotated description of all the tables created and maintained by an iIS process engine. The iIS process engine automatically creates these tables when the engine is cold started and maintain their contents during normal operations. You can use the information provided here to write queries against the tables for management information on current and past process instances. However, you should avoid altering the rows in the tables (with the exception of periodically flushing history tables of rows that are no longer needed).
Some tables are for internal use only, and are unlikely to be useful for any management queries. The documentation on these tables is limited.
The data type description for each entry in a table is based on the representation used in Oracle databases. The actual data type may differ, depending on the database vendor you are using.
NOTE The schema presented here may differ from the schema for previous versions of iIS. Also, the schema is subject to further change in future versions.
