Abstract

Until recently, databases tended to focus on current information only, but now it is possible to keep historical information as well. A temporal database system is one that includes special support for the time dimension of data. It provides special features for storing, querying and updating temporal data. The purpose of this paper is to explain various techniques involved in designing and using temporal databases. We described some of the issues that arise in temporal databases and showed how they might be addressed in a relational database management system. Our approach to temporal data was based on dealing with intervals as such. The UNPACK operator was a crucial conceptual component of our approach to the management of temporal data in particular. We covered a range of advanced temporal concepts that could be applied to temporal database design, temporal database updates, and the formulation of integrity constraints and temporal queries. Temporal database support was added to the SQL standard in the 2011 edition of that standard. Therefore, we introduced some of the temporal features of the SQL standard.
