_TL: Table ending with _TL is a Translation Table. Such tables have a column called language

_B: Tables ending _B are the base tables

_VL: Tables ending with _VL are Views built upon multi language or translation tables. In other words such views combine base table data with translation table data. If you wish to see the data related to a one particular language, you should set the language using USERENV(‘LANG’).

_A, _Avn, _ACn: Tables ending with _A, _Avn, _ACn are audit tables.
