An MDM Hub Master Database is associated with a set of Operational Reference Stores. Decide how many Operational Reference Stores to create. Also, decide whether you want to distribute the Operational Reference Stores across multiple machines. Your decision determines the installation topology.

If you have a large database management system, you can set up multiple MDM Hub environments. For each MDM Hub environment, you must set up an MDM Hub Master Database with its own tablespaces, a unique ActiveVOS schema, and a set of Operational Reference Stores. You can set up multiple MDM Hub environments in a single database instance or multiple database instances.
