Conceptual Modeling Through Fuzzy Logic for Spatial Database (original) (raw)

Fuzzy logic shows a degree of vagueness or uncertainty that is expressed with crisp spatial objects. It supports spatial database objects which can precisely determine shape and boundaries. The uses of fuzzy logic with spatial database for conceptual modeling handles uncertain data types in fuzzy object-oriented database. Fuzzy approaches have been extensively applied for modeling different databases to explicitly represent and manipulate the imprecise and uncertain data precisely. In this paper, a new conceptual modeling approach has been developed and studied on the case of traffic modeling and route identification problem.
