The Computers: Software: Databases: (Data Mining Databases )

An automated analysis of structured electronic data, such as in a data warehouse, which is intended to discover previously unrecognized patterns and relationships between data items. It differs from OLAP and other forms of query-driven data analysis in that patterns are determined by the system using statistical algorithms, thereby uncovering relationships for which the user hasn't developed a query. Human analysis of the statistical patterns is then required to determine the reasons for the emerging relationships. Data Mining Databases Software Computers.

The term is a misnomer, because the goal is the extraction of patterns and knowledge from large amounts of data, not the extraction ( mining ) of data itself. (wikipedia)
