DataSources.config
This file contains data source definitions for use by the Teradata.Net and Oracle.Net data providers. These definitions include connection information and (optionally) a list of Databases to be loaded into the Database Explorer Tree and the color bar to be displayed in the query window for this data source
This file is re-written each time the application is shut down.
Note: There might also be a DataSources.config file in the ‘All Users’ branch. That file contains system level data sources. The application never updates it.
