Rolls back the transaction in action. It will end all database activity, since commiting a transaction is finalizing it. After calling Commit or Rollback, the ITransaction implementing class will reset itself. When used in combination of COM+, it will call ContextUtil.SetAbort() to abort (rollback) the current COM+ transaction.

Rolls back the transaction in action to the savepoint with the name savepointName. No internal objects are being reset when this method is called, so call this Rollback overload only to roll back to a savepoint. To roll back a complete transaction, call Rollback() without specifying a savepoint name. Create a savepoint by calling Save(savePointName)
