Abstract

In heterogeneous multiple query processing environments, usually the query processors depend upon estimated database cardinalities when evaluating the cost of the query plans. In this paper it is being projected to retrieve query plans along with their costs and fitness values by applying join selectivity techniques for relations used in query processing by applying genetic algorithm techniques. It has also been aimed to see that whether the evaluation of selectivity factor of sub query operation may be feasible and may reduce the total query cost.
