Can anybody tells me what is database overlap? or is there any article that i can refers to? any help will be appreciated. Thanks

take a look this

And here we have a perfect example of the dangers of 'googling-up' an answer . Jemacc, if you'd read the page at the end of your link, you'd see that it was an article about a TCP vuln! Nothing to do with databases, except for the mention of the 'X-Force Database' in the page navigation bar:(.
leion, if you tell us why you are asking, we might have a better idea of what the answer might be. A quick browse through Google's top results seems to indicate it's more of a database theory term than a specific problem for SQL server. Of course, someone out there might actually have an answer off the top of their head...:)

There are two secrets to success in this world:
1. Never tell everything you know

Even though is not related to database, it gives a starting point of where to start gathering information. Not everyone has a definite and specific answer to a request for information. I am sorry that it was you who responded and not the one that posted the request for information. If you feel the information is not to your satisfaction do not apply it to your immediate need.

To:Leion:
Excuse me if I miss-directed you to information not worth reading

To Chrislepingwell: Do you have an original idea. You must of found the same search on Google. (by the way;google is not the only search engine out there)

i think chriss made a good point in his post.

leion, did you found what you were looking for after all?
