Advances in data gathering, storage and distribution have created need for computational tools and techniques to aid in data analysis, data mining and knowledge discovery data base. It is a rapidly growing area of research and application that builds on techniques and theories from many fields including statistics, databases, pattern recognition and learning, data visualization, etc. The topic is based on data mining, which is the process of extraction of unknown and potentially useful information from data in databases. Various tools and algorithms are used in the process of data mining. It is a relatively new concept, which is advancing in recent years. At present we go through the evolution, foundation, tools, techniques and problems faced by data mining.
