A great deal of recent work in computer science applies itself to temporal database design.
Designers of geographical information systems (GIS) can build on this work to create a …

The relational algebra is a procedural query language for relational databases. In this paper
we survey extensions of the relational algebra that can query databases recording time …

Recently, attention has been focused on temporal databases, representing an enterprise
over time. We have developed a new language, Tquel, to query a temporal database. TQuel …

A temporal database contains time-varying data. In a real-time database transactions have
deadlines or timing constraints. In this paper we review the substantial research in these two …

This paper summarizes the major concepts, approaches, and implementation strategies that
have been generated over the last fifteen years of research into data base management …

Many applications require the ability to manipulate sequences of data. We motivate the
importance of sequence query processing, and present a framework for the optimization of …

We propose a generalized relational model for a temporal database which allows time
stamping with respect to a Boolean algebra of multidimensional time stamps. The interplay …

Non-temporal data models and their implementations as database management systems
(DBMS) capture a single state of the real world, usually the current one. They support …

In this paper we discuss extensions to the conventional relational algebra to support both
aspects of transaction time, evolution of a database's contents and evolution of a database's …
