One of the main techniques for solving this problem is Data Mining.Data mining (DM) is the process of identification and extraction of usefulinformation in typically large databases. DM aims to automatically discover theknowledge that is not easily perceivable. It uses statistical analysis and  artificial intelligence (AI) techniques  together to address the issues. There aredifferent types of tasks associated to data mining process. Each task can bethought of as a particular kind of problem to be solved by a data mining algorithm.The main types of tasks performed by DM algorithms are:•   Classification:•   Association:•   Clustering:•   Regression:•   AnomalyDetection:•   FeatureExtraction• Time Series AnalysesIn this paper we will perform a survey ofthe techniques above. A secondary goal of our paper is to give an overview ofhow DM is integrated in Business Intelligence (BI) systems  .BI refers to a set of tools used formultidimensional data analysis, with the main purpose to facilitate decisionmaking. One of the main components of BI systems is OLAP. The main OLAPcomponent is the data cube which is a multidimensional database model that withvarious techniques has accomplished an incredible speed-up of analyzing andprocessing large data sets. We will discuss the advantages of integrating DMtools in BI systems.
