| Abstract: | Rules for mapping between SAM * data model and relational data models are the basis of query anddata translation in semantic DBMS being developed.Mapping rules are established in this paper,andprotype model design is given.The problem that semantic lost in translat process is solved by useing dic-tionary system. |
