data source name (DSN)

Contributor(s): Beth Kane

(DSN also stands for Deep Space Network .)

A data source name (DSN) is a data structure that contains the information about a specific database that an Open Database Connectivity ( ODBC ) driver needs in order to connect to it. Included in the DSN, which resides either in the registry or as a separate text file, is information such as the name, directory and driver of the database, and, depending on the type of DSN, the ID and password of the user. The developer creates a separate DSN for each database. To connect to a particular database, the developer specifies its DSN within a program. In contrast, DSN-less connections require that all the necessary information be specified within the program.

There are three kinds of DSN: user DSNs (sometimes called machine DSN s); system DSN s; and file DSN s. User and system DSNs are specific to a particular computer, and store DSN information in the registry. A user DSN allows database access for a single user on a single computer, and a system DSN for any user of a particular computer. A file DSN contains the relevant information within a text file with a .DSN file extension, and can be shared by users of different computers who have the same drivers installed.
