Requirements for managing change history of data are increasing with the advanced usages of databases. To meet the requirements, a number of temporal DBMS's have been developed. But, each DBMS has its own interface and its own concept of time. Thus, the user has to be acquianted with each DBMS. In this paper, we describe design of an integration scheme of heterogeneous temporal DBMS's.
