In 4D v11 SQL, 4D Tools is no more!
4D Tools functionality has been incorporated directly into 4D and is now part of the 'Maintenance and Security Center' or 'MSC' for short. The MSC is your one-stop shop for information about your structure and datafile as well as repairing, compacting and other maintenance options to ensure your database is running smoothly.
You can get to the MSC from the Toolbar or by selecting the Help Menu -> Maintenance Security Center.
You can also open the MSC from within 4D code using OPEN SECURITY CENTER.
