        Oh dear, it was crossposted.

        I wasn't talking about predicate calculus, I was talking about a complete middle-tier business logic tier. But let's not go there, I don't want a discussion about that with people who think everything except perhaps the bare-bones gui should be inside an RDBMS system. let's agree to disagree on that, we just share different views on that topic.

        Which part of "So I can't comment on..." don't you understand?

        that's your interpretation, I just wanted to formulate that what his experiences were could be the result of wrongly applied OOP, which could perfectly be caused by his teammembers, or by a skewed project description or whatever.

        That's great to know, it wasn't in the posting. Again, my goal wasn't to judge the poster's knowledge, just that it's perfectly possible to have bad experiences with OO like with any technology/method, and thus that could influence how you think about it.

	so, all you want is just flame me. Cool, have fun, Bob.
