 ## How did we solve the problem?
 
-You were able to quickly create a local copy of a database for development and testing purposes. With a single command, you created a new local instance and restored the most recent backup to it. You then ran another command to connect to it via Azure Data Studio. You then queried the database using [!INCLUDE [name-sos-short](../../includes/name-sos-short.md)] to check for data quality issues.
