About this wizard
This wizard steps you through the process of creating a connection to the target database you want to reverse engineer.
To create a connection, you specify an installed Visio driver and the 32-bit ODBC (Open Database Connectivity) data source. For convenience, before you run the wizard, you should set the default Visio driver and target database to the target database you want to reverse engineer.
The schema definition information that the wizard can extract depends upon a combination of things, such as the capabilities of the DBMS (Database Management System) and ODBC driver. To the extent that it is available from the target DBMS, you can select the schema definition information that the Reverse Engineer Wizard will extract.
