Working with data sources
After you’ve added a data source, you can specify options for external FileMaker data sources and ODBC data sources.
To access external FileMaker data sources, you define a reference to that file. See Editing external FileMaker data sources.
To access ODBC data sources, you must set up a driver for the data source, connect to the data source name (DSN), identify the tables you want to work with in the external file, and then add the external table in the relationships graph. See Editing ODBC data sources.
