Abstract: As Web service technologies are firmly established and widely adopted, traditional transaction semantics and protocols are proved to be inappropriate for some Web services-based applications. This paper proposes a Web services transaction model, and researches two-phase commitment extended protocol, coordination algorithms and transaction compensation. This model has the advantages of flexibility and practicability in transaction, and provides powerful support for commercial Web services.

Key words: Web services, Transaction, Model, Two-phase commitment extended(2PCE)
