Using Tabular Models - SQL Server Analysis Services 2012 Cube Development - page 306

3. Once you have set these details, click on OK to create the project. This will
create a new solution, a new project, and a development database on your
tabular instance.
Note
If you have a local Tabular Model instance of SSAS, the project will point
to that. However, if the project cannot discover the tabular instance, you
will be prompted to select the instance to be used for the project.
4. In the project's solution explorer, you will see your project and a Model.bim
file. This file is the container for your Tabular Model. However, as I mentioned
before, the actual development requires a tabular instance.
Note
Only one BIM file will exist in the project. Tabular database projects only
support one model.
5. If you open up SQL Server Management Studio and connect to your tabular
instance, you will see a new tabular database, which has the name of the
project, the name of the user, and GUID to make up the name.
