Algorithms of Buffer Management in Active Real-Time Database System

Active real-time databases have emerged as a research area in which concepts of active databases and real-time databases are combined into real-time database with reactive behavior. Such systems are envisioned as control systems for environments as diverse as process control, network management and automated financial trading. Sensors distributed throughout the system report the state of the system to the database. Unacceptable state reports typically results in corrective actions being triggered with deadlines. This paper is a study of various buffer management techniques in real time database management system & active real time database management system as well as we implemented few of them. We created ARPLRU (Active Real-Time Priority LRU) and ARPHA (Active Real-Time priority hint algorithm) and compared with PAPER algorithm.
