Define SQL Server Database Roles

A role uses Windows security accounts to limit the scope of access and permissions when users access the database. A database role specifies a set of database level permissions that let a user perform specific tasks. Database roles are not fixed and can be created, modified, and removed. Database roles let you collect users into a single unit to which you can apply permissions. You can define a set of roles based on job functions and assign each role the permissions that apply to that job.

Use the SQL Server Database Role Editor to define database role objects in a SQL Server 2008, 2012, 2014 or 2016 physical model.
