The CData ODBC Driver for CouchDB can be used from any platform or development technology that supports ODBC, including PowerBuilder. This article shows how to connect to CouchDB data and execute queries from the Database Painter and controls such as the DataWindow.

Connect to CouchDB as an ODBC Data Source

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.
