Notes on the demo:

This SQLChallenge does NOT require restoring a database. The setup script generates all the databases you need. See the scripts and videos for full details.

This demo will NOT work as-is in Azure SQL Database. That’s because accessing multiple databases requires setting up External Tables and using Elastic Database Queries in that “Platform as a Service” solution.
