Oxford English Dictionary (2004)

Note

A data warehouse contains data which is built out of separate internal and/or external data sources where the data is integrated in a consistent manner. The database design of a data warehouse favours data analysis and reporting in order to gain strategic insight and to facilitate decision-making. A data warehouse contains “fact tables” and “dimension tables” which may be arranged as a “star schema” or a “snowflake schema”
