Even after going through many resources, I have failed to understand what constitutes a lakehouse, hence my question below.

If we have Azure Gen 2 Storage, ADF, and Azure Databricks with the possibility of converting the incoming CSV files into Delta tables can that be called a "Lakehouse" architecture or is it called a "Delta Lake"?

Or is it the "SQL analytics" engine over and above the Delta Lake layer that makes it a "Lakehouse"?

Please clarify.
