Introduction (to data mining) In today's world, knowledge is power. An important source of knowledge is the data stored in databases. Data allows us to learn from the past and to predict the future. With the rapid computerization of businesses and organizations, a huge amount of data has been collected and stored in databases, and the rate at which data is stored is growing at a phenomenal rate. As a result, traditional ad hoc mixtures of statistical techniques and data management tools are no longer adequate for analyzing this vast collection of data. Data mining (or knowledge discovery in databases or KDD in short) has emerged as a growing field of multidisciplinary research for discovering interesting/useful knowledge from large databases. KDD is defined as the extraction of implicit, previously unknown, and potentially useful patterns from data.
Over the past few years, research and development in data mining has made great progresses. A large number of research and application papers have appeared in the literature. Many successful applications have been reported in various sectors such as marketing, finance, banking, manufacturing, and telecommunications. Some examples of business applications include: Using data mining techniques to analyze customer databases so that potential customers can be selected more precisely; Using data mining techniques to detect fraud - from detecting cellular cloning fraud to identifying financial transactions that may indicate money-laundering activities. Data mining systems typically help businesses to expose previously unknown patterns in their databases. These information "nuggets" are used to improve profits, enhance customer service, and ultimately achieve a competitive advantage.
