Read Only specifies whether InfoMaker should update the extended attribute system tables and any other tables in your database. The extended attribute system tables (also known as the extended catalog) consist of five tables that contain default extended attribute information for your database.
The Read Only setting determines whether you can modify (update) the tables in your database. By default, the Read Only check box is cleared in the Database Preferences dialog box. This means that InfoMaker updates the extended attribute system tables and other tables in your database when you make changes.
If you select the Read Only check box, InfoMaker does not update the extended attribute system tables or any other tables in your database. You cannot modify (update) information in the extended attribute system tables or any other database tables from the Form or DataWindow painters when the Read Only check box is selected.
