Describing Integrity Constraints in Advanced Database Systems
In advanced database applications, specifying integrity constraints in a declarative way allows to maintain the database consistency so that the database satis es the integrity constraints. By associating each data with its status, in this paper, we show the consistency information of advanced database applications can be expressed declaratively by a set of clauses, which are classi ed into fou...
متن کاملKnowledge Systems in Agroforestry
Pacific Islands agroforestry has evolved into sustainable, diverse and productive a land use systems in many areas. We marvel at these systems, and the scientific world is trying to catch up with the traditional knowledge. At the same time, Pacific Islands farmers are abandoning their agroforestry systems in great numbers. It is mainly intensified agriculture for cash crop production that follo...
متن کاملIntegrity Constraints in OWL
In many data-centric semantic web applications, it is desirable to use OWL to encode the Integrity Constraints (IC) that must be satisfied by instance data. However, challenges arise due to the Open World Assumption (OWA) and the lack of a Unique Name Assumption (UNA) in OWL’s standard semantics. In particular, conditions that trigger constraint violations in systems using the ClosedWorld Assum...
متن کاملSpatial Clustering in SOLAP Systems to Enhance Map Visualization
The emergence of the SOLAP concept supports map visualization for improving data analysis, enhancing the decision making process. However, in this environment, maps can easily become cluttered losing the benefits that triggered the appearance of this concept. In order to overcome this problem, a post-processing model is proposed, which relies on Geovisual Analytics principles. Namely, it takes ...
متن کاملActive Integrity Constraints for Multi-context Systems
We introduce a formalism to couple integrity constraints over general-purpose knowledge bases with actions that can be executed to restore consistency. This formalism generalizes active integrity constraints over databases. In the more general setting of multi-context systems, adding repair suggestions to integrity constraints allows defining simple iterative algorithms to find all possible gro...
