Meta Data

Guide to Data Warehousing and Business Intelligence

Meta data is simply data about data.  It includes a definition of each field in the Data Warehouse and the corresponding domain values.  Meta data describes where the data came from and how it was transformed or cleansed during the data integration process.

Because warehouse data can originate from multiple sources and is used for critical decision making, it is important that data definitions be clear and accessible to all Data Warehouse users.
