Abstract: To obtain a correctly integrated schema which corresponds to the modeled real world, integrity constraints have to be considered in the schema integration process. Previous publications on this area focused on the integration of object constraints as well as certain class constraints like uniqueness constraints. In this paper, we discuss the ability to integrate aggregation constraints which are integrity constraints that are based on aggregate functions like min, max, avg, sum, and count. For... (Update)
