Technical report TR94-15. In this paper we describe an implementation of a temporal relational database management system based on attribute timestamping. For this purpose we modify an existing software which supports set-valued attributes. The algebraic language of the system includes...

Temporality in Object Database Management Systems
1998
Technical report TR98-04. Conventional databases represent the state of an enterprise at one particular point in time. That is, they contain only current data. As a database changes, out-of-date information, representing past states of the enterprise, is discarded. However, temporal support is a...
