File extension dsn is commonly used by many various database applications for various configuration or settings files. These can have a form of settings, drivers and other parameters, that are used by ODBC drivers to connect to a specific database, such as Microsoft Access database or SQL Server.

To an ADO or RDS programmer, an ideal world would be one in which every data source exposes an OLE DB interface, so that ADO could call directly into the data source.

Although increasingly more database vendors are implementing OLE DB interfaces, some data sources are not yet exposed this way. However, virtually all DBMS systems in use today can be accessed through ODBC.
