-If your automation process involves connecting to a SQL Server database and manipulating data directly on the runner machine, you would typically need SQL Server or a SQL Server client installed on the runner machine.
-If your automation process connects to a remote SQL Server database, you do not necessarily need SQL Server on the runner machine.
-Database in Orchestrator: In this case, the runner machines do not need SQL Server installed because the database operations are handled by the Orchestrator.
-Depending on your specific use case, you might not even need a full SQL Server installation.
