There are huge number of legacy SQL databases with old codes and gotchas across the world. If MS can build a connector that imports all these tables into CDM it will literally free up SQL DBA job positions. Every app will have database IN UI! without a need of DBA.. If this connector is built many old apps can be easily converted to powerapp.
Provided primary, FK are imported. Also in powerapps it will be amazing if master detail forms can be build auotmatically based on these CDM tables.
