Instances of objects in the Business Data Connectivity object model are tied to the Metadata Store they are obtained from. Using instances tied to one Metadata Store with the instances from another Metadata Store will cause data corruption and other unexpected behavior. For more information, see DatabaseBackedMetadataCatalog, FileBackedMetadataCatalog, and RemoteSharedFileBackedMetadataCatalog.
