Group

A Group is generally created to simplify Permissions and Access Controls. When a number of Users all need the same Permissions (for example: to use Functionality in Management Studio), it makes sense to create a Group for those Users. After the Users have been added to the Group, Permissions and Access Control can be configured for the Group and all the Permissions and Access Control changes will be applied automatically to the Members of that Group. Groups can belong to one or more Groups and Roles.
