ERwin Naming Standards allows to enforce the abbreviation standards for words when deriving physical model from logical model ( In other words it helps us in following the database objects naming convention as set by the DBA in a consistent manner).
This feature also lets us enforce the word order and the position of words ( like prime, modifier1, modifier2, class you can read more about these words and what they mean in Bookshelf that comes with ERwin data modeler Install)
