"Advanced" refers to authentication model. The "Advanced" authentication model allows multiple users to login to the Bound Book and also allows the users to be restricted via predefined application roles.
That’s all there is to creating the book. By default the user specified above is the “Owner” of the SQL Server Bound Book database that was created on the server. At the moment there is only one user configured for this bound book and that is the user that created it.
In order to configure other users to open the bound book refer to “Configuring Users / Roles in an Advanced SQL Bound Book”.
