A New Transaction Scheduling Scheme for Active Real-time Database Systems: Space-Filling Curve

This paper presents the space-filling curves and their applicability in scheduling, especially in transaction scheduling in Active Real-time Database Systems (ARTDBS). Active real-time databases have emerged as a research area in which concepts of active databases and real-time databases are combined into a real-time database with reactive behaviour. A novel space-filling curve based approach for scheduling transaction in active realtime database systems is described along with generalized transaction model for active real-time database system is given which is used as base model for transactions in active real-time database system. This paper addresses proposed space-filling curve approach is detailed followed by its comparative evaluation with different algorithms used in ARTDBS.
