The Teradata BI Model Repository is a small dedicated database that stores the cube metadata that you enter into Teradata Schema Workbench. The repository does not store any cell data and especially not any pre-aggregated data.
The SQL grant scripts are being provided to let you see the names of the tables in the Teradata BI Model Repository and are only published in this appendix for reference purposes. Notice the three key roles being created and assigned to about two dozen small tables.
