Sage Database Structure

Our Sage local DB environment was setup in 2017 hosted on a Windows Server 2016. I am attempting to gain access to the data. Currently an active SQL Instance is named SAGESQLGATEWAY and when connected to it, only lists SqlGatewayConfiguration database. When checking under C:\Program Files\Microsoft SQL Server\MSSQL11.SAGESQLGATEWAY\MSSQL\DATA I can see there is MSDBData database and I believe that's where the data is stored. Can you explain the database structure for Sage Accounting, or perhaps there's a document that would better answer where the data is stored and the proper DB configuration?
