Distributed real time database systems: background and literature review

Abstract: Today's real-time systems (RTS) are characterized by managing large volumes of dispersed data making real-time distributed data processing a reality. Large business houses need to do distributed processing for many reasons, and they often must do it in order to stay competitive. So, efficient database management algorithms and protocols for accessing and manipulating data are required to satisfy timing constraints of supported applications. Therefore, new research in distributed real-time database systems (DRT… Show more

“…Most of the previous works on real-time database systems are concentrated on soft real-time systems, such as stock trading systems (Adelberg et al, 1995;Amirijoo et al, 2006;Kang et al, 2004) and traffic information systems, with the main performance goal to maximize the average performance of the systems, e.g., minimizing the number of deadline missing transactions or maximizing the freshness of data objects (Shanker et al, 2008;Kang et al, 2009;Ramamritham et al, 2004;Lam and Kuo, 2001;Lam et al, 2002;Abbott and Garcia-Molina, 1992). With the rapid advancements in wireless communication and sensor technologies in recent years, real-time database technologies are gaining increasing interests for applications into various time-critical surveillance systems.…”

“…Real-time data objects are defined for describing the current status of dynamic entities in an operation environment such as the location of a moving object and the temperature of a production engine Shanker et al, 2008). Unlike the data objects in conventional database systems, a realtime data object has a temporal validity constraint (Ramamritham, 1993).…”

“…The sensors track the current status of dynamic entities either on the robot or in the physical operation environment. They publish measurements through update transactions [20,29] to be installed into a real-time database [28] in the robot controller. Another common example is a smart home system where various sensors work together for tracking moving objects and detecting intruders.…”

“…In a database system, the basic unit o f processing is a transaction, w hich is a set o f read/write operations that can be either local or global [1], Local transactions deal w ith data The lifetime o f a transaction can be divided into two phases: a w ork phase and a commit phase [9]. In its work phase, a transaction reads or manipulates data.…”

“…In today's world, almost every business uses a database system. Access to a database system is controlled by transactions, w hich are combination o f read operations that read data from the database systems and w rite operations that update data in the database systems [1]. A ccording to Berstein and N ew com er [2], a transaction must follow ACID properties: atomicity, consistency, isolation, and durability.…”
