There are several different types of Subscription Views that can be created in MDS, in order to deliver data in the appropriate way for external systems.

The Subscription Views are model-level objects that are bound to either a version or a version flag. Binding the Subscription View to a version will mean that the resulting SQL Server view only contains data for that version (for example, our 2011_Stores Version). On the other hand, binding to a version flag will mean that it is always possible to extract a version dynamically, as the subscription view is bound to a version flag and the version flag is then bound to a version.

All of the objects that we covered back in Chapter 4 can be extracted, namely Entities, Derived Hierarchies, Explicit Hierarchies, and Collections.
