A datawarehouse typically supplies answer to a question like 'who is buying our products/". A data mining approach would seek answer to questions like "Who is NOT buying our products?".

Simple stated that data mining is the KDD Knowledge discovery in large databases. In this hidden patterns are meant to be discovered.
The typical query of data mining is "Tell me something I don't know". How can you tell some one the thing he doesn't know all about, means you cannot write query  to answer this question. So you try to discover some thing using intelligent techniques. As the volume of data is very large for mining so we need fast algorithms, usually run time for mining is O(n) or O(nlogn). O(n2-[n square]) is a kill.
