The rapidly growing amount of data exceeds the human ability to understand them without the mediation of powerful tools. In such case, the stored data are an archive material, which is rarely visited and used. Consequently, the decisions are made based on the intuition of decision makers, but not on the basis of information and knowledge extracted from the data, which are stored in databases. Data mining is the nontrivial extraction of implicit, previously unknown and potentially useful information or knowledge from large dataset. It is a carefully planned and complex process that consists of the following
