Oracle Database Discussions

Names of schema elements often contain acronyms (ID, US, PO, GPS etc.) and word abbreviations (Ref, Num, Dpt, Qty, Nbr), making data integration more uphill. My intuition is that abbreviations/acronyms in schemata of relational DBs have a specific nature (e.g. often non standarized and created ad hoc). I would like to verify my intuition with some real-world schema, especially one that could contain abbreviations and acronyms.

Can you recommend me some real-world schema ?

Best,
