The Future Lab database engine Bbuuzzb uses two types of tables; user and system. A user table is a normal table opened by some sort of user program/process. A system table is opened internally by the database engine or server. The following tables are classified as system tables:
The session table and system catalog are used when the particular feature is enabled. Temporary tables are used by the database engine when some sort of data has to be temporarily saved.
System tables have no entry in the system catalog, are not saved and restored to the session table and cannot be replicated.
