That certainly is half the battle; probably more IMO.  From initially doing
95% of my code OO, I've leveled off at about 20%, if even that, and have
discovered better mantainability, performance and overall design.

With some work, there are ways to emulate stored procedures as far as middle
and front-end work is concerned.  But you're right, stored procs can be hard
to beat.

There's quite a buzz about SAPDB.  I'm anxious to get some time and play with
it, and I've heard many good things so far.  SAP themselves are renowed
business DB designers and it's good to see this kind of activity from them.

This has been my only hesitation to aggressively pursue SAPDB.  ODBC has
scared me in the past and I alway prefer to use native APIs where possible. 
I'll be curious to hear if you run into any issues with ODBC->SAPDB.

And oh, there's always PostgreSQL... pooooor ol' PostgreSQL  :)
