6 A Practical Architecture of Distributed Real-Time Main-Memory Databases for Modern SCADA Systems

As the automated control systems have been applied to various aspects of everyday life including industrial control, oil mining, building automation and traffic scheduling, the strong flexibility and the high real-time performance of modern SCADA (Supervisory Control and Data acquisition) systems, especially their core — real-time databases, are in urgent need. In this paper, a practical architecture of the distributed real-time main-memory database is proposed, with the help of which, a modern SCADA system would be flexible enough to configure differently for different application, while still easily meet the requirements of the rigid time constraints.
