From some time back, I was working on Oracle object dependencies. Oracle itself, is the director of all dependencies. I have compiled some of the concepts like dependency checks and verification, Fine grained concepts and version enhancements. Got the same published with Exforsys Inc. Check the same and post your queries/feedback/comments.
Surely, it must thrust you to dig more into it. I shall be happy to see the reviews.
