    I guess real world experience just doesn't cut it with you guys. I clearly

    said that the RDBMS that we were using, was just not up to the task!     And BTW, it was the best RDBMS available at the time. Yes I can see     Bob's point that we lost a lot of things, but I was still responsible for meeting

    the requirement and because of the highly specialized nature of the application,

    we never missed the other attributes that Bob mentioned.

    Don't get me wrong. I am not an ODBMS bigot. There are just certain applications

    that are better served by using an ODBMS. This happened to be one of them.

    It was highly specialized, had a very complex data model and we used OO technology

    to build the applications business logic. All of which lend themselves very well to

    the use of an ODBMS as a persistent store.

    Ok Alfredo, I can see now that there's just going to be no talking to you

    or Bob on any sort of adult level.

    Bob i've read more then my share of good books in the areas that most     interest me and are important to my profession. Datasbase technology     just happens to be one small subset of a much larger whole that I have     to take into account on each project that I take part in.

    There is if you keep liberally spreading the term throughout your responses.

    Read Bob response to your response. I think he actually managed to use     the word "ignorant" in every single sentence he wrote.

    Bob, have you ever added anything worth reading to this forum? I've     been a long time silent reader of this forum and I can't remember when     I have ever read anything even mildly useful in any of your posts. In fact,

    I know that if I open one of your posts i'm going to see snide remarks     and personal attacks and no meaningful content. The whole thing with the     f*^k you response was priceless. You're burning your bridges before     you're even getting to them. Seek help Bob, seek help.
