| 摘 要： | 本文针对工程领域的特点，提出基于关系／网状的语义超图模型描述，以表达工程中不同语义类的多对多复杂对象关系；将该模型描述和表达的管理机制和基本数据在内存中统一管理和运行，使工程数据的存取效率大为提高；增加了大量通用和特殊功能，形成了功能更强、使用方便的Ｃ语言界面．在上述基础上自行研制并有自主版权的工程数据库管理系统ＥＤＢＭＳ（ｅｎｇｉｎｅｅｒｉｎｇｄａｔａｂａｓｅｍａｎａｇｅｍｅｎｔｓｙｓｔｅｍ）已在建筑ＣＡＤ领域中得到实际应用.

| Abstract: | According to the features of engineering domains, this paper presents a semantic hypergraph model based on relation and network, in order to express many to many relations of different semantic classes. The management mechanism expressed by the model and the basic data of databases are managed and run in main memory, thus the access efficiency of engineering data is increased. C language interface which includes general and spacial functionalities is proposed for meeting requirements of engineering applications. The EDBMS(engineering database management system) with above research results is implemented and has been actually used for engineering domains. |
