Methods and systems for maintaining transaction semantics in a computer system

摘要

An interface is used to manage nested atomic transactions, in which a transaction participant can also be a transaction manager. These transactions include fundamental and/or composite commands. Each command is represented by a command object, and the interface is implemented by methods and variables in each of these command objects. The interface enables a transaction manager to instruct its transaction participants to perform prepare and commit or rollback phases and to ascertain whether the prepare phases succeed or fail. The interface enables any command object to be a transaction manager and a transaction participant.
