Release 10.1A: OpenEdge Data Management:

Virtual system tables

Virtual system tables (VSTs) provide 4GL and SQL access to system statistics. You can use this information to help analyze database and application design, as well as to determine what factors are impacting database performance. The virtual system tables, or schema tables, have no physical records until the database manager generates them at run time. For a detailed description of each table, see Chapter 25, " Virtual System Tables."
