| Summary: | Checking the consistency of a database state generally involves the execution of integrity tests on the database,
which verify whether the database is satisfying its constraints or not. This paper presents the various types
of integrity tests as reported in previous works and discusses how these tests can significantly improve the
performance of the constraint checking mechanisms without limiting to a certain type of test. Having these test
alternatives and selecting the most suitable test is an issue that needs to be tackled. In this regard, the authors
propose a model to rank and select the suitable test to be evaluated given several alternative tests. The model
uses the amount of data transferred across the network, the number of sites involved, and the amount of data
accessed as the parameters in deciding the suitable test. Several analyses have been performed to evaluate
the proposed model, and results show that the model achieves a higher percentage of local processing as
compared to the previous selected strategies. |
