    Strategic decision making process uses a lot of GroupBy clauses and join operations queries. As the source of information in this type of application to these queries is commonly very huge, then parallelization of GroupBy-Join queries is unavoidable in order to speed up query processing time. In this paper, we investigate three parallelization techniques for GroupBy-Join queries, particularly the queries where the group-by clause can be performed before the join operation. We subsequently call this query “GroupBy-Before-Join” queries. Performance evaluation of the three parallel processing methods is also carried out and presented here.
