The Connection object is used to create an open connection to the data source. It is used to send

store, update or fetch the data from the database. Connection object enables a Web developer to
work with SQL server, OLEDB, ODBC, or Oracle database.

exists for the life of the transaction. It should be released when the transaction completes. It is used
to begin, commit, or roll back a transaction.

manager and a transaction object on which the resource manager has enlisted.

resource manager.
