Questions tagged [datasource]

Datasource is a name given to the connection set up to a database from a server. The name is commonly used when creating a query to the database. The database source name (DSN) does not have to be the same as the filename for the database.

A data source is any of the following types of sources for (mostly) digitized data:

  • a database (in the Java software platform, datasource is a special name for the connection set up to a database from a server)
  • a computer file
  • a data stream

Please see more here (Wikipedia entry for Datasource) and here (Java 6 Datasource interface documentation)
