Viv,

So, I just made a very unpleasant discovery - I guess I will have to share it with other developers - we are up to a big disappointment - re-factoring :(

Apparently, most of our code happens on the client :(((( In other words, we're getting all data back to the client and then do all operations. Since we're working with relatively small development database, we didn't notice bad performance (only in certain areas).

But imagine clients with millions of rows :(
