A knowledgeable person can use this dialog to work directly on the database. This would normally only be accessed by you when you were working with a programmer or troubleshooter to investigate or correct some difficulty. In most cases the Visual Traffic support person would hook up to your server by modem and access the dialog directly. You should consult with Visual Traffic support if you suspect something is wrong.
This dialog allows direct access to the SQL database without using the VT dialog which has many internal checks to prevent someone from causing damage. There are far fewer restraints with this tool. Never attempt to use this dialog by yourself. You could severely damage all or part of the integrity of your database by using this "programmers" tool.
