Abstract
This paper investigates the applications of Labelled Deductive Systems (LDS) as a framework for the development of a computational formalism for the description of active historical databases. This formalism is then applied to the study of retroactive updates. The propositional temporal logic USV/Z for temporal validity is presented and we prove its soundness and completeness. The historical data model is derived from an LDS framework for this logic. The mechanism for the execution of active temporal rules is described, showing how retroactive updates can cause the appearance of non-supported actions. An extension of LISWZ into a non-monotonic LDS is applied for the detection of such actions.
