Data Warehouse PDF: Data Warehousing Concepts (Book)

A data warehouse is built to support management functions whereas data mining is used to extract useful information and patterns from data. Data warehousing is the process of compiling information into a data warehouse. Data Warehousing : It is a technology that aggregates structured data from one or more sources so that it can be compared and analyzed rather than transaction processing.
