A vendor is authenticated for use of a retailer's data warehouse and limited access rights are assigned to the vendor for access. The vendor accesses a graphical user interface (GUI) to select an available analysis module for execution against the data warehouse. Schemas are presented in the GUI based on the access rights, and specific schema selections are made by the vendor. The analysis module is then configured and executed against the data warehouse and filtered results are presented to the vendor; the results filtered based on the access rights assigned to the vendor.
