Other than creating a flowchart, Microsoft Visio is also a very good tool for data modeling. The default database driver set on the software though is for Microsoft Access.
Here are the steps to change the target database driver to SQL Server or any other available databases:
Make sure you have other database driver you want to use installed on your computer first.
Go to the Database menu, then click Database Drivers.
On Database Drivers window under Drivers tab, select Microsoft SQL Server as the default driver for Visio and click OK.
That’s it. Now when you open the column property (Edit button), you see the new default driver.
