However, existing web service transaction management technologies have some shortcomings, such as difficulty in rolling back transactions when a transaction fails, leading to inconsistent system status.This paper proposes a web service transaction flexibility compensation technology to address these problems. This technology classifies possible abnormal situations that may occur during the web service transaction execution process and designs corresponding compensation measures for different abnormal situations. The technology proposed in this paper has high flexibility, can adapt to different application scenarios, and can avoid the inconsistency caused by rolling back transactions.精品文档---下载后可任意编辑This paper starts from the basic concepts of web service transactions and related technologies, introduces the advantages and disadvantages of existing web service transaction management technologies, and then focuses on the design ideas and implementation methods of web service transaction flexibility compensation technology proposed in this paper. Finally, through experiments, this technology is tested and evaluated for performance, and the results show that this technology has high efficiency while ensuring transaction consistency.Keywords: Web service, transaction management, flexibility compensation, distributed system
