Data mining, also known as knowledge-discovery in databases (KDD), is the practice of automatically searching large stores of data for
meaningful patterns (knowledge). With advances in the process of data
collection, 1990s saw an explosion in growth of data. This coupled with the
stellar advances in computing technologies really spruced up "Data
Mining".
Data mining has been defined as "The nontrivial extraction of implicit, previously unknown, and potentially useful information from data" [1] and "The science of extracting useful information from large data sets or databases" [2]. Although it is usually used in relation to analysis of data, data mining, like artificial intelligence, is an umbrella term and is used with varied meaning in a wide range of contexts.

Why is data mining needed ?
The two high-level primary goals of data mining in practice tend to be prediction and description. Prediction involves using some variables or fields in the database
to predict unknown or future values of other variables of interest, and description focuses on finding
human-interpretable patterns describing the data.
The goals of prediction and description can be achieved using a variety of particular data-mining
methods like,
and many more.
