An Evaluation of QoS Management Approaches in Real-Time Databases

In this paper we propose an evaluation model of QoS (Quality of Service) management approaches in real time database management systems (RTDBMS). In our model we define three evaluation levels: Models, Parameters and Policies. Each level is composed by a set of evaluation criteria. Our model is illustrated by an evaluation study of principale existing approaches of QoS management in RTDBMS. We aim to help designers of real time database management systems to choose the most appropriate QoS management approach corresponding to their real time application requirements.
