The RGMATupleStore structure holds details of a user's permanent tuple store. The type field will be RGMAStorageType_DATABASE. Tuple stores are always created by R-GMA. Users who wish to access a database tuple store from outside of R-GMA should call RGMAPrimaryProducer_listTupleStores or RGMASecondaryProducer_listTupleStores to obtain the database URL, then contact their system administrator to get direct access to the database.
