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 th...
متن کاملDealing with the Fuzziness of Human Reasoning
Reasoning, the most important human brain operation, is characterized by a degree of fuzziness. In the present paper we construct a fuzzy model for the reasoning process giving through the calculation of probabilities and possibilities of all possible individuals’ profiles a quantitative/qualitative view of their behaviour during the above process. In this model the main stages of human reasoni...
متن کاملEvent Processing in Mobile and Active Database Systems Using Broadcasts
The integration of active database technology into mobile database systems allows to limit the transfer of data between mobile computers and the stationary network. In order to employ such active database mechanisms, the rule processing component of traditional active database systems needs to be modified. This paper introduces a new model for event processing and presents a new algorithm for t...
متن کاملMixed concurrency control: Dealing with heterogeneity in distributed database systems
A mixed concurrency control, which allows the two techniques two phase locking and certification to coexist together in the same distributed dambase system, proves to be advantageous in a number of situations : interconnected databases, static or dynamic heterogeneity of transactions or objects. In this paper we propose a method which seems well adapted to the majority of the forms of heterogen...
متن کاملActive Database Systems
Integrating a production rules facility into a database system provides a uniform mechanism for a number of advanced database features including integrity constraint enforcement, derived data maintenance, triggers, alerters, protection, version control, and others. In addition, a database system with rule processing capabilities provides a useful platform for large and e cient knowledge-base an...
