An effective assemble-oriented framework for grid Web service based on open grid service architecture was proposed,in which Web service semantics network constructed by software reuse was designed to enhance the locating of assemble-oriented service resources.The successful Web services assembled structure was exploited to design semantics network,the logical and the physical structure of the resource was separated in Web service,and the logical resource derived from type ID of Web service was combined with semantic structure.The organizing protocol,data structures and the mechanism of implementation in the model were presented.Experiment results show that the success ratio of Web service request comes to 100% while providing completely assembly semantics set.This model provides guarantee of the reliability of assemble Web service and establishes the foundation of Web service automatic interaction,customizing application service and dynamic service configuration.
在以电子病历(Electronic Medical Record)为核心的HIS医院信息管理系统中,病历数据的管理是其核心内容。介绍了电子病历中不确定时态数据的概念及表示方法,进一步,在Delphi编程环境中深入讨论了不确定时态数据的瞬时过滤、期间过滤的设计原理及编程方法,从而有效地展示了电子病历中不确定时态数据在过去某个时刻或期间的医疗情况。
