Abstract

There is a noticeable interest in merging standard database technology and real-time technology recently, resulted in combined systems known as Real-Time Database Systems. They are similar to the conventional databases, but they must ensure some degree of reliability regarding the real-time response requirements. It is very difficult to achieve guaranteed real-time database services in terms of both deadline miss ratio and data freshness because various components can compete for system resources. Transactions travel in a RTDB system through various components until their termination. Our objective is to design an experimental real-time database system which would be suitable enough to study the most important real-time database issues, including CPU scheduling, concurrency control and conflict resolution. Because of the strong interactions among the processed components, proposed system can help us to understand their effect on system performance and to identify the most important factors.
