通过对CIMS信息集成要求的分析 ,结合NGC CIMS分类编码系统的具体情况 ,提出了码位依赖关系。在对直接依赖、组合依赖和扩展组合依赖分析的基础上 ,就这三种依赖关系提出了码位模式分解和基于元关系的解决方法。最后根据NGC CIMS分类编码系统的实施情况 ,指出了这种方法的有效性
Based on the analysis of CIMS information integration requirements and the specific conditions of NGC CIMS classification and coding system, the code bit dependency is proposed. Based on the analysis of direct dependency, combination dependence and extended portfolio dependency, this paper proposes the solution of the code bit pattern decomposition and the meta-relationship based on the three kinds of dependencies. Finally, according to the implementation of NGC CIMS classification coding system, the validity of this method is pointed out
