E. Zimányi, C. Parent, S. Spaccapietra, and A. Pirotte. TERC+: a Temporal Conceptual Model. In Proceedings of the International Symposium on Digital Media Information Base, DMIB'97, Nara, Japan, November 1997.

Abstract

Much work has been done recently on the design of a temporal extension to SQL-92, called TSQL2. Similar work is being done to add temporality to the forthcoming SLQ3 standard. Still, TSQL2 is based on the relational model, which is hardly adequate for conceptual modeling of any but the simplest applications. This paper presents a temporal conceptual model, called TERC+, that can be used for developing applications with temporal features in a practical and realistic way. The model allows to describe application data structures independently of implementation concerns. We then define the semantics of TERC+ as a mapping to relational schema constructs.
