以腐蚀数据共享需求为切入点,结合软件的发展趋势即网络服务,采取目标取向设计(OOD/A),建立适合于开放网络环境下的通用腐蚀数据模型.以XSD作为设计母语,创立腐蚀数据标记语言CDML.通用腐蚀数据模型和CDML语言是开放网络环境下腐蚀数据交换和信息整合的核心及介质.基于腐蚀数据特征及相互关系分析,提出“数据岛”概念,“数据岛”作为自备性腐蚀数据的根节点,包含六个一级子节点以刻画腐蚀数据的完整性,自备性和相对独立性.详细讨论了各级关键节点的意义以及在模型层次结构中的作用.分析介绍了CDML及基于Java程序语言的公共应用程序界面API的结构和组成,并探讨了它们在多源数据整合和信息共享平台中的作用.
Taking the demand of data sharing as a starting point and combining with the trend of software development, that is, network service, the OOD / A design is adopted to establish a common corrosion data model suitable for open network environment. XSD is used as design language to establish corrosion data Marker language CDML. The common corrosion data model and CDML language are the core and medium of corrosive data exchange and information integration in open network environment.Based on the analysis of corrosion data characteristics and interrelationship, this paper proposes the concept of data island, data island, "As the root node of self-prepared corrosion data, it contains six first-level sub-nodes to characterize the integrity, self-protection and relative independence of corrosion data.It discusses in detail the significance of key nodes at all levels and their significance in the model hierarchy The structure and composition of common APIs based on CDML and Java programming languages are analyzed and discussed, and their roles in multi-source data integration and information sharing platform are discussed.
