What is a data warehouse?
A data warehouse is a database constructed for quick searching, retrieval, ad hoc queries, and ease of use. A data warehouse is composed of both detail and summary data which are normally extracted periodically from an operational database or from a public information service. A data warehouse is an effective means of collecting, standardizing, and assimilating data from diverse sources, and may consume hundreds of gigabytes or even terabytes of disk storage. Most organizations implement a data warehouse as part of a strategic IT initiative that involves an ERP system. The creation of a data warehouse separate from operational systems is a fundamental data warehousing concept.
