RTDS: A COMPONENT AND ASPECT-BASED REAL-TIME DATABASE SYSTEM SIMULATOR

The demand for real-time data services has increased lately. Applications like stock markets, embedded systems and telecommunications arc becoming more demanding real-time database management systems (RTDBMS). Research in the area of real-time databases leads to the development of sophisticated control algorithms and components and for testing these in different configurations we need a simulator framework that allows us to see how they behave for different transaction workloads. As a means for evaluating real-time database algorithms, we have developed RTDS, Real-Time Database Simulator, a simulator which is based on components and aspects. RTDS is fully configurable and has the ability of simulating a real-time database with differentiated services and distinct configurations. Using well-defined components, an application can use a RTDBMS with only the required functionalities starting with an architecture based on very simple admission control to quality of service support based on feedback control.
