TDBTransaction encapsulates a SQL transaction. It is an abstract class, and should be used by component creators that wish to encapsulate transactions in a class. The TDBTransaction class offers functionality to refer to a TDatabase instance, and to keep track of TDataset instances which are connected to the transaction.
