DSN

A DSN (Data Source Name) is an identifier which defines a data source for an ODBC driver.

A DSN consists of information such as:

• Database name
• Directory
• Database driver
• User ID
• Password

Under Unix, DSN configuration is usually stored in /etc/odbc.ini.

Under Microsoft Windows, DSN configuration is normally stored in the registry, although it may also be stored in configuration files with a .dsn extension.
