This class encapsulates a client-initiated database transaction. You can start a transaction, provided you have an open connection, by calling the SqlConnection.BeginTransaction( ) method, which returns a SqlTransaction object. The SqlTransaction class implements the System.Data.IDbTransaction interface, and its members are described in that section of the reference.

You can also use the Save( ) method to create a savepoint, which is similar to a nested transaction. (This method is equivalent to Transact-SQL SAVE TRANSACTION statement.) You must supply a string that names the savepoint. You can then roll back the transaction to an intermediate point using the overloaded version of the Rollback( ) method that accepts the savepoint name. Savepoints are useful when you want to be able to roll back part of the transaction without canceling the entire transaction.
