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.
