Controlling access to SQL table metadata
To restrict access to application metadata and prevent users from altering core SQL tables, system administrators can use the Metadata Access Controls form. The restrictions apply when users modify tables in the SQL Tables form, the SQL Columns form, and the UET Table/Class Relationships form.
Note:
Currently, system administrators can use the Metadata Access Controls form to restrict access only to SQL tables. The Metadata Access Controls form is accessible only to authorized system administrators and is read-only in multi-tenant cloud environments.
