Metadata or META Data Metadata is data about data. Examples of metadata include data element descriptions, data type descriptions, attribute/property descriptions, range/domain descriptions, and process/method descriptions. The repository environment encompasses all corporate metadata resources: database CATALOGS, data dictionaries, and navigation services. Metadata includes things like the name, LENGTH, valid values, and description of a data element. Metadata is stored in a data dictionary and repository. It insulates the data warehouse from changes in the schema of operational systems. Metadata Synchronization The process of consolidating, relating and synchronizing data elements with the same or SIMILAR meaning from different systems. Metadata synchronization joins these differing elements together in the data warehouse to allow for easier access.
