A Multidimensional Model for Information Quality in Cooperative Information Systems
نویسندگان
چکیده
Cooperative Information Systems implement cross-organization processes by exchanging information among each other in a mutual supplier--customer relationship. With respect to the quality of the information received, each customer system has requirements that must be met by its supplier systems. In this paper, we model the quality profile associated to a supplier as a multidimensional data cube, show how requirements can be formally expressed by referring to views over the cube, and thus provide a precise notion of adequacy of the supplier with respect to its customers' requirements, and a way for customers to rank their suppliers with respect to the quality profile they offer.
