Addressing Efficiency Issues During the Process of Integrity Maintenance

چکیده
We address efficiency issues during the process of integrity maintenance. In this sense, we propose a technique that improves efficiency of existing methods by defining the order in which maintenance of integrity constraints should be performed. Moreover, we integrate view updating into integrity maintenance and we propose a technique for translating view updates efficiently, aimed at reducing the number of alternatives considered during the process of view updating and the EDB accesses required to perform this translation.

Structuring the Process of Integrity Maintenance
Two different approaches have been traditionally considered for dealing with the process of integrity constraints enforcement: integrity checking and integrity maintenance. However, while previous research in the first approach has mainly addressed efficiency issues, research in the second approach has been mainly concentrated in being able to generate all possible repairs that falsify an integ...

متن کاملConsistency preserving updates in deductive databases
Several problems may arise when a deductive database is updated. The problems that are addressed in this paper are those of integrity constraint maintenance and view updating. In this sense, we define a method that tackles both problems in an integrated way and that it is sound and complete. We also propose an architecture for our method to deal with both problems efficiently. Improvement of ef...
متن کاملAssessment of distance-based multi-attribute group decision-making methods from a maintenance strategy perspective
Maintenance has been acknowledged by industrial management as a significant influencing factor of plant performance. Effective plant maintenance can be realized by developing a proper maintenance strategy. However, selecting an appropriate maintenance strategy is difficult because maintenance is a non-repetitive task such as production activity. Maintenance also does not leave a consistent trac...
