Hi Boris,

Thanks for your answer.

UoW and other patterns are present in more or less every ORM system I know of. I don't use any pattern for the sole purpose of using a patter. We faced some problems which could be solved with these patterns and so far I don't know any other solution. Our component under development is huge and as previous discussions have shown we push ODB to its limits. Luckily we didn't push it beyond them yet ;)

That's what it already looked like to me. Thanks for the confirmation.
