Our company is in process of purchasing an object database tool which has a good
C++ binding in Unix environment. So, far we have come up with three choices, which we
need to select one:

    1) Objectstore
    2) Versant
    3) Objectivity

We are wondering if anybody has used these tools and have any feed back and lessons
learned in real application. Your response would be greatly appreciated.


                                                             Thanks AS.
