Teradata Meta Data Services (MDS) is software that creates a repository in the Teradata Warehouse in which metadata is stored. The Teradata MDS repository is a set of tables that resides in the Teradata Database.
MDS also permits the DSS analyst to administer and navigate metadata in the warehouse.
For application developers, MDS provides a persistent store for application metadata so that
developers can concentrate on developing application functions.
MDS provides a single shared copy of metadata, or a single version of the truth. One copy eliminates multiple islands of redundant metadata that can cause confusion and administrative difficulties. MDS maintains the metadata so that the application is kept current with warehouse database changes.
