Abstract
The design and implementation of real-time database systems presents many new and challenging problems. Compared with traditional databases, real-time database systems have a distinct feature: they must maintain temporally coherent data while satisfy timing constraints associated with transactions. In addition, a real-time database system must adapt to changes in the operating environment and guarantee the completion of critical transactions. In this paper we address the issues associated with temporal nature of transactions and data, and research areas for advanced real-time database systems.
