摘要
为实现装备全寿命周期大量异构数据源之间的信息共享和交换,解决异构装备数据源的集成和互操作问题,提出了面向装备全寿命周期信息集成的公共数据模型EHDM.给出了EHDM的定义和描述方法,以两类典型的装备数据源模型为例,研究了EHDM对高层数据模型的建模方法.定义了普通高层数据模型到EHDM以及EHDM之间的转换操作.最后给出了基于EHDM的集成过程实例,实现异构装备全寿命周期数据源的模式集成.
To realize the information sharing and exchanging among a large scale of heterogeneous data sources in equipments lifecycle, and solve the problems of integration and interoperability for heterogeneous equipments data sources, we propose a common data model named EHDM for the equipment lifecycle information integration. Give the definition and description of EHDM, and illustrate the modeling process for high level data models using EHDM by two typical kinds of high-level data model. Define the transformation operations among EHDM models and high-level data models. Give an instance of the integration process based on EHDM, which realize the schema integration for heterogeneous lifecycle equipment data sources.
