SAP HANA / Oracle

In the ERP world I have always been in the Oracle E-Business camp. Nothing against SAP just never had any reason to work with it but know a few lads who do. Obviously, Oracle 'E-Biz' has an Oracle database at the back of it and most SAP sites use Oracle too (as far as I can tell) even though SAP is database independent. I feel SAP and E-Biz is a bit like the Solaris or Linux, X-Box or PS4 debate. It really depends on what you want.

However HANA which is a in memory "vertical" database and is supposed to be very quick can be used with SAP and is prob one of the reasons why you might go down the SAP road. Oracle have had "TimesTen" around for a long time but I have never worked anywhere that would pay for it or had a need to use it. 

There is a lot of debate on the web but if anyone has any real world experience of both please let me know. Really quick in-memory databases are great but for a lot of sites they want a Ford Transit for load not a Ferrari for speed.
