Dealing with Fuzziness in Active Mobile Database Systems

Current needs of industry required the development of advanced database models like active mobile database systems. An active mobile database system can be designed by incorporation of triggering rules into a mobile computing environment in which the users are able to access a collection of database services using mobile and non-mobile computers at any location. Fuzzy concepts are adapted to the ®eld of databases in order to deal with ambiguous, uncertain data. Fuzziness comes into picture in active mobile databases especially with spatial queries on moving objects. Incorporating fuzziness into rules would also improve the e€ectiveness of active mobile databases as it provides much ̄exibility in de®ning rules for the supported application. In this paper we present some methods to adapt the concepts developed for fuzzy systems to active mobile databases. Ó 1999 Published by Elsevier Science Inc. All rights reserved.
