Design and Implementation of TEMPO Fuzzy Triggers ================================================= by Tarik Bouaziz, Janne Karvonen, Antti Pesonen and Antoni Wolski Technical Report TTE1-2-97, VTT Information Technology, Espoo, Finland, March 1997, 21 pp. Abstract Fuzzy triggers are database triggers incorporating fuzzy concepts. The approach leads to the application of approximate reasoning to trigger-based decision making. In C-fuzzy triggers, fuzzy rules may be specified in the trigger condition part. The concepts of fuzzy terms, linguistic variables and fuzzy rules are introduced. The C-fuzzy trigger model is presented, and an implementation thereof in the TEMPO ServerÑa prototype active database systemÑis described. The performance test results are included.
