An Improved QSQI Query Algorithm

OSQI is one of the query algorithms of logic database It is of the feature of top-down,iteration disposal,so that it has a faster querying speed than Naive and Semi-naive methods.However,much redundancy still exists during the iteration computation The improved QSOI queryalgorithm reduces the redundancy to some extent.This paper gives its principle and compares it withOSOI by an example.
