This short blog shows you where to find the SSAS database that you deployed.
After you deployed the SSAS cube in Visual Studio and you started SQL Server Management Studio then choose Analysis Services. You did not get to see the database you deployed.
The reason is, only the Administrator can see the SSAS database, I am not sure why is Microsoft doing that. It seems this is only way I can resolve this for now. This is SQL Server 2012, the newest version might have change the behavior, I am yet to try test.
