Database Object Security (Master Data Services)
Applies to: 
SQL Server - Windows only
Azure SQL Managed Instance
In the Master Data Services database, data is stored in multiple database tables and is visible in views. Information that you might have secured in the Master Data Manager Web application is visible to users with access to the Master Data Services database.
Specifically, employee salary information might be contained in an Employee model, or company financial information might be in an Account model. You can deny a user access to these models in the Master Data Manager user interface, but users with access to the database can view this data.
You can grant permissions to database objects to make specific data available to users. For more information on granting permissions, see GRANT Object Permissions (Transact-SQL). For more information about securing SQL Server, see Securing SQL Server.
The following tasks require access to the Master Data Services database:
Staging Data
In the following table, each securable has "name" as part of the name. This indicates the name of the staging table that is specified when an entity is created. For more information, see Overview: Importing Data from Tables (Master Data Services)
| Action | Securables | Permissions |
|---|---|---|
| Create, update, and delete leaf members and their attributes. | stg.name_Leaf | Required: INSERT Optional: SELECT and UPDATE |
| Load the data from the Leaf staging table into the appropriate MDS database tables. | stg.udp_name_Leaf | EXECUTE |
| Create, update, and delete consolidated members and their attributes. | stg.name_Consolidated | Required: INSERT Optional: SELECT and UPDATE |
| Load the data from the Consolidated staging table into the appropriate MDS database tables. | stg.udp_name_Consolidated | EXECUTE |
| Move members in an explicit hierarchy. | stg.name_Relationship | Required: INSERT Optional: SELECT and UPDATE |
| Load the data from the Relationship staging table into the appropriate MDS tables. | stg.udp_name_Relationship | EXECUTE |
| View errors that occurred when data from the staging tables was being inserted into the MDS database tables. | stg.udp_name_Relationship | SELECT |
For more information, see Overview: Importing Data from Tables (Master Data Services).
Validating Data Against Business Rules

Configuring System Settings
There are system settings that you can configure to control behavior in Master Data Services. You can adjust these settings in Master Data Services Configuration Manager or if you have UPDATE access, you can adjust these settings directly in the mdm.tblSystemSetting database table. For more information, see System Settings (Master Data Services).
