more SAP notes

1. ABAP (Advanced Business Application Programming) is the language of SAP.
2. SAP 4.6 is quarter century old (yes, the 80s) and is no longer supported by SAP AG itself. Yet, if you are an SAP developer you may have to deal with this stuff. As you modify an existing deployment it gets harder and harder to upgrade and some companies are still trapped in the 4.6 world.
3. Oracle has only 200 to 300 corporate entities using its Oracle eBusiness Suite ERP, but SAPs numbers are in the thousands.
