Facts mining could be outlined because the means of choice, exploration and modelling of enormous databases, that allows you to notice versions and styles. The expanding availability of information within the present details society has ended in the necessity for legitimate instruments for its modelling and research. information mining and utilized statistical tools are the perfect instruments to extract such wisdom from facts.

This chapter will also focus on the first phase of frequent pattern mining, which is generally considered more important and non-trivial. Frequent patterns satisfy a downward closure property, according to which every subset of a frequent pattern is also frequent. This is because if a pattern P is a subset of a transaction, then every pattern P ⊆ P will also be a subset of T . Therefore, the support of P can be no less than that of P . The space of exploration of frequent patterns can be arranged as a lattice, in which every node is one of the 2d possible itemsets, and an edge represents an immediate subset relationship between these itemsets.
