摘要
在语义数据库管理系统中,模型转换是查询转换和数据转换的基础,本文探讨了SAM模型向关系模型转换过程和转换规则,并给出了原型设计,为了防止转换过程中语义丢失,本文利用字典解决这一问题.
Rules for mapping between SAM * data model and relational data models are the basis of query and
data translation in semantic DBMS being developed.Mapping rules are established in this paper,and
protype model design is given.The problem that semantic lost in translat process is solved by useing dic-
tionary system.
