A conceptual approach for dealing with imprecision and uncertainty in object-based data models
M.A. Vila, Juan-Carlos Cubero, Juan Miguel Medina, Olga Pons · International Journal of Intelligent Systems · 1998
This article treats the problem of vagueness in databases from a general point of view. Several kinds of attribute imprecise values are considered, including the case where such values are fuzzy set of objects. The possibility of managing uncertain data is also taken into account and both sources of the lack of information are studied jointly. All these vague elements are represented in a unified manner by using a semantic data model. The article shows how this representation is possible and opens the way for implementing this kind of information by using a classic object-oriented database system. © 1996 John Wiley & Sons, Inc.
