I believe these changed significantly from V7.5 to V10. I did a partial analysis under 7.5 by opening tables and looking for known entities such as users, scorecards etc. SAP never published such a model. Perhaps it is time to do the same under 10. Note that under 7.5 the table prefix gave the subject area, e.g. CPMS_EA for entry and approval, CPMS_DM for diagram manager (strategy map).
