1. Microsoft Fabric documentation on Shortcuts: "Shortcuts in Microsoft Fabric allow you to reference data across domains
clouds
and accounts without copying the data. Once a shortcut is created to a table in another lakehouse
it appears in the table list of the lakehouse and can be queried like any other table."

2. Microsoft Fabric documentation on Cross-database querying: "Microsoft Fabric enables you to share data between lakehouses and warehouses without moving or duplicating data. You can create a shortcut in a lakehouse that points to a table in another warehouse or lakehouse... Once the shortcut is created
you can write T-SQL queries that join tables across the three-part named databases."

3. Microsoft Fabric documentation on Lakehouse SQL endpoint: "Every Lakehouse has a SQL analytics endpoint... The SQL analytics endpoint enables you to query data in the Lakehouse using T-SQL language." This establishes that each lakehouse is a distinct queryable database context
necessitating a mechanism like shortcuts to bridge them.
