On extended fuzzy relational database model with proximity relations
In this paper, Shenoi and Melton's model of fu2zy relational database is considered. Proximity relation, being an important tool of the model, is characterized theoretically. An optimal alpha -distribution in [0, 1] and consequently the domain partition are defined, and studied with examples on fuzzy queries. (C) 2001 Elsevier Science B.V. All rights reserved.
