| 摘 要： | 由于缺乏丰富的语义处理能力,传统的数据库管理系统对日益扩大的数据库领域(如CIMS等)越来越不能相适应,开发一种具有处理复杂数据类型、动态模式定义、支持版本控制的DBMS势在必行。而支持DBMS进行管理的核心是字典系统。本文以SAM*模型为基础,探讨了适合于SAM*DBMS的字典系统的设计与实现技术,提出了以字典作为关系映射的思想。

| Abstract: | With the development of database,relational DBMS dose not meet the needs of wider and wider ap-plication proccess ability.So it is neccessary to develop a new kind of DBMS,which can process complexdata type,support version control,dynamic schema definition and so on.Basis SAM~* data model,thispaper make on inqury into the design and implimentation technologe of semantic data dictionary systemwhich is a core part of DBMS,and propose the idea of using data dictionary as tool for relation mapingand data management. |
