When you create a link between a Microsoft Office Visio drawing and a database, you use
a Data Source Name (DSN) made in the Open Database Connectivity (ODBC)
administrator. DSNs contain information about where the database
is stored and which driver to use, and they have unique names so you
can find them easily for later use.
When you use the Export to Database dialog box, the Database Export
Wizard, the Database Wizard, or the Link to Database command, you choose
a DSN. If you haven't already created a DSN, you can make one from
within the wizard or dialog box. The Create New Data
Source wizard will guide you through the process.
Tip
It's handy to choose a name for the DSN that reflects the name of
the database it connects to.
If you make a File DSN, it is typically stored in a default location,
c:\Program Files\Common Files\ODBC\Data Sources. If you choose a
different location as you go through the Create New Data Source wizard,
you'll need to browse to find it if you go through a database
connectivity wizard or dialog box again.
After you complete the Create New Data Source wizard, the ODBC Setup
dialog box appears, in which you can either select an
existing database or create a new one.
Note If you're using Microsoft Office Excel as a data
source, you can't create a workbook from within the wizard. You can only
choose an existing one.
Tip
If you choose an Excel workbook, be sure to uncheck the Read Only
check box in the Select Workbook dialog box.
