The Data Dictionary tables are created during system initialization (sysinit), by the Database Initialization Program, or both. The tables store information about the system (system metadata) that is essential for it to function. The information is also essential to users that are responsible for managing the system.

The system automatically updates the information in the tables to reflect the current state of the system.
