Termination properties of spatial Datalog programs,tial queries must be established by ad-hoc arguments, if it can be established at all. As an illustration of the difficulties that can be encountered in this respect we discuss the topological connectivity query.作者: Halfhearted 時(shí)間: 2025-3-22 04:08 作者: 不連貫 時(shí)間: 2025-3-22 06:40
An axiomatic interpretation of confidentiality demands in logic-based relational databases,hat many security properties can already be proved from these few axioms. These properties characterise a mandatory-security-policy-conforming database with an unequivocal semantics of the data and a notion of integrity identical to that of relational databases.作者: defenses 時(shí)間: 2025-3-22 12:07
Applying transition rules to bitemporal deductive databases for integrity constraint checking,could violate some integrity contraint. Although, we have a large amount of transition rules, for each one we argue its utility or we eliminate it. We augment a database with this set of transition and event rules and then standard SLDNF resolution can be used to check satisfaction of integrity constraints.作者: Abjure 時(shí)間: 2025-3-22 16:00
Formal characterization of active databases,struct [SZ90] to characterize the non-determinism that arises when several rules can fire at the same time and the preference between them is not specified.

Learning query rules for optimizing databases with update rules,pdate rules)..In order to cope with these difficulties, we study storage optimization, and then, we propose to use Machine Learning techniques in order to compute new query rules, so that the semantics of the resulting database contains the semantics of the original one and satisfies our optimization criterion.作者: Palate 時(shí)間: 2025-3-23 23:53
