Data mining is part of a larger process called Knowledge Discovery in Databases (KDD). The discovery part of the process – the part that finds gold among the gigabytes-is data mining. But before you can pull out your tin pan and shake it for gold, you need to gather your data into a data warehouse.

The Difference Between Data Mining and KDD -

Data mining is a step in the KDD process of applying data analysis and discovery algorithms that, under acceptable computational efficiency limitations, produce a particular enumeration of patterns (or models) on the data. Note that the pattern space is generally infinite and the enumeration of patterns involves some form of search that space. We use two primary mathematical formalisms for the
