A data source name (DSN) is a unique name that identifies a data source. A data source can be a database, a file, or a message queue. A DSN can be created by a user or by an application. A DSN is stored in a data source definition (DSD) file.
When a DSN is created, the following information is stored in the DSD file:
• The data source type (database, file, or message queue)
• The data source name
• The data source location
• The data source user name (if applicable)
• The data source password (if applicable)
A DSN is used to connect to a data source. When a DSN is used, the data source location and login information are retrieved from the DSD file.
