Research on Web Services Transaction Processing Model Based on Agent

As one of the experiment units of the Shanxi Province Scientific Data Sharing Program launched in 2006,the Taiyuan Science Data Sharing Network(referred to as TYSDS) provides basic data services for research.Through the application of software architecture and Web Service technology,it is designed as a platform of distributed five-story structure,namely website portal, sharing business tier,the core services tier,the data resource management and network platform tier.Driven by user requirements,the general center's functions are designed as a "data supermarket",and they are developed through metadata techniques.Distributed sub centers are developed by Web Services techniques.All the function modules between general center and sub centers are organized according to the life cycle of metadata in the data sharing business.The TYSDS prototype system is developed with the cross platform program and applied within the Taiyuan Scientific Data Sharing Program.
