Using Fuzzy Theory to Information Predicate for Improvement of Cache Operation in Mobile Databases

New achieves in wireless network technology, satellite services and cellular communication allows to usage of mobile computing. This mobility is troublesome for doing mobile computing that need to retrieve information from database. System movement during transaction execute, causes to disconnection of mobile unit from wireless network and this disconnection due to transaction abort and mobile system have to redo transaction from start. One of methods that used to prevention of transaction abort is using of cache in mobile units. The information that need to current transaction execution, are saved in cache. Prediction and sending Appling additional information for mobile unit in order to prevention of transaction abort during disconnection of mobile system with wireless network. Our goal of this work is present a solution for prediction information for send to mobile unit in order to use cache operation with usage fuzzy theory.
