以嵌套集合模型管理国际社区医疗分类（ICPC）的整体实现

作为现代区域社区医疗卫生信息平台建设中不可缺少的基础医学信息，在系统设计和开发过程中的一个重要基础是标准化。国际社区医疗分类（ICPC）作为区域社区医疗卫生信息平台必备的标准化数据字典之一，其对整个区域社区医疗卫生信息平台的重要性不言而喻。故在实际系统开发层面上如何整体实现值得程序开发人员认真的考量。针对国际社区医疗分类（ICPC）字典在关系型数据库中提出了处理分层数据统一的数据嵌套集合模型，在此基础上讨论了分层数据结构编程的有关问题，主要为建立和管理数据集、分层数据结构的检索、节点的增加、删除等一般性操作处理。以及分层数据结构在用户界面上的表现方式等。

To the Nested Set Model for Management of the International Classification of Primary Care (ICPC) as a Whole to Achieve

As a modern regional community medical and health information platform for building an indispensable basic medical information in the system design and development process is an important basis for standardization. The International Classification of Primary Care （ICPC） as a regional community health information platform for standardized data necessary the dictionary, one of its communities throughout the region the importance of medical and health information platform is self-evident. However, in actual system development level, how to achieve the overall program developers should be careful consideration. In this paper, the international community medical classification （ICPC） in the dictionary relational database, the data presented to deal with hierarchical nested set of unified data model, on the basis of the hierarchical data structure discussed issues related to programming, mainly for the establishment and management of data sets, hierarchical data structure, retrieval, node increase, delete, etc. dealing with the general operations, as well as the hierarchical data structure in the performance of the user interface methods.
