Data mining is the method of finding patterns in large data sets involving methods at the intersection of machine learning, statistics and database systems. It is the process of extracting potentially useful information from huge amount of data. It uses a group of methods to organise, examine and combine large data sets, including machine learning, visualisation methods and statistical analyses. Data mining is used in computational biology and bioinformatics to discover trends or patterns without knowledge of the meaning of the data. It is an interdisciplinary subfield of computer science and statistics with a common goal to mine useful information from a data set through intelligent methods and to transform the information into a understandable format for further use
