| Description | An important problem that arises when updating a deductive database is the one related to integrity constraints maintenance. That is, given a consistent database and an update request, to obtain all possible ways of updating the base facts such that the request is satisfied while consistency of the database is maintained. This problem becomes more complex when view updates may also be requested since these updates must be translated into base fact updates. In this paper we present a method for providing automatic support in these situations. Our method takes into account information about the keys of the predicates and it is able to handle updates which consist of a set of insertions, deletions and/or modifications of base and derived predicates. Our interest in this paper is to describe the current status of our work towards providing an effective and efficient method for updating consistent deductive databases. 1.
