摘要

Many decision support applications such as task assignment, truck deliveries, airline screw scheduling problems usually need to get information from objects with many-many relationship. However, current relational operators including the complete set of relational algebra and other relational operators are difficult to get required information from objects with many-many relationship. In this paper, we extend SQL so that users can capture more information from objects with many-many relationship by using the query language directly. The relational operators were extended with six operators, namely, match, maxmatch, cover, mincover, partition, and minpartition.
