Tally ODBC

With Open Database Connectivity you can dynamically exchange data between Tally.ERP 9 and any other application dynamically.

You must ensure that MS-Query is installed on the computer in which you will be installing Tally.ERP 9. This enables ODBC as soon as Tally.ERP 9 is installed.

The ODBC server is displayed on the information block of the information pane.
