摘要
Web服务的出现对分布式事务提出了新的需求,为了保证多个Web服务交互获得正确的执行和一致性的结果,有必要为Web服务提供事务机制。但是Web服务具有松散耦合性、运行时间长等特点,这使得传统的事务处理技术在处理Web服务事务时显得力不从心。本文对Web服务事务的关键问题进行了阐述,包括Web复合框架的事务性支持、Web服务事务规范以及扩展事务模型等方面的研究内容,并指出了目前研究的不足以及未来的发展趋势。
As Web service technologies have become firmly established and widely adopted, traditional transaction se- mantics and protocols have proven to be inappropriate for some Web services-based applications. These particular Web services-based transactions differ from traditional transactions in that they execute over long periods, they re- quire commitments to the transaction to be negotiated at runtime, and isolation levels have to be relaxed. In this pa- per, we present a survey on various aspects of the research of Web service transactions, including Web service com- posite framework, extended transaction models, Web service transaction specifications and so on. Lástly, we try to give an indication of where Web service transactions will go in the future.
