If you upgrade the database on one computer, all connected computers also need to be upgraded. If the upgraded database isn't compatible with the current application version, you'll encounter numerous system errors. When it comes to updating software, it's important to make sure only the right people can do it. By controlling who can update the software, we can protect our systems from problems that might happen if someone makes changes without permission
