Abstract

A substantial number of temporal extensions to data models and query languages have been proposed. However, little attention has been paid to the migration of data and applications from a "snapshot" DBMS to a temporal extension of it. In this paper, we analyze this issue and precisely formulate some requirements related to it. We then present a temporal extension of the ODMG's object database standard fulfilling these requirements. Throughout this presentation, we underscore the importance of providing adequate update and interpolation modalities in achieving application migration support.
