Define SQL Server Application Roles

A role uses Windows security accounts to limit the scope of access and permissions when users access the database. An application role allows access to specific data to only those users that connect through a particular application. Application roles contain no members and are inactive by default. Application roles work with both authentication modes. Access to other databases is limited to permissions granted in those databases to Guest. A database in which Guest has been disabled cannot be accessed by application roles in other databases.

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