Virtual system tables
Virtual system tables (VSTs) provide ABL and SQL applications access to the same database information that you can collect with the PROMON utility. The virtual system tables, or schema tables, have no physical records until the database manager generates them at run time. This enables an ABL or SQL application to retrieve information as run-time data.
