Implementing a Temporal Database on top of a Conventional Database: Mapping of the Data Model and Data Definition Management

Patrícia Nogueira HublerNina Edelweiss

Researches concerning Temporal Databases are being developed for more than 20 years.However, very few implemented systems are available. Several temporal data models were proposed, extending traditional data models in a way to capture also the temporal features. A feasible way of implementing a Temporal Database is using a conventional commercial database mapping the temporal data model to it. This mapping shall provide the explicit representation of the temporal information related to the intended temporal data model. A Temporal Management System is presented in this paper. Data and rules related to a temporal data model are managed by this system, implemented on a conventional DBMS.
