Safety Verification of Real Time Systems Serving Periodic Devices
In real-time systems response to a request from a controlled object must be correct and timely. Any late response to a request from such a device might lead to a catastrophy. The possibility of a task overrun, i.e., missing the deadline for completing a requested task, must be checked and removed during the design of such systems. Safe design of real-time systems running periodic tasks under th...
متن کاملIssues in Developing Object-Oriented Database Systems for Real-Time Applications'
Database systems for real-time applications must satisfy timing constraints associated with transactions, in addition to maintaining data consistency. Recently, interests in object-oriented databases have been growing for nontraditional applications of database systems, and several real-time applications are being developed using an objectoriented paradigm. The object-oriented approach seems pr...
متن کاملValue-Driven Multi-Class Overload Management in Real-Time Database Systems
In complex real-time applications, real-time systems handle significant amounts of information that must be managed efficiently, motivating the need for incorporating realtime database management into real-time systems. However, resource management in realtime database systems is a complex issue. Since these systems often operate in environments of imminent and transient overloads, efficient ov...
متن کاملActive Real-Time Database Systems
Real-time systems are systems where the correctness of the system not only depends on the logical result of a computation, but also when the result was produced. In complex real-time applications, real-time systems have to handle a signiicant amount of information which requires to be handled eeciently, motivating the need for incorporating real-time database management modules into the real-ti...
متن کاملResearch Issues in Real-Time Database Systems
Today's real-time systems are characterized by managing large volumes of data. Efficient database management algorithms for accessing and manipulating data are required to satisfy timing constraints of supported applications. Real-time database systems involve a new research area investigating possible ways of applying database systems technology to real-time systems. Management of real-time in...
متن کاملDRDB: Towards distributed real-time database services for time-critical active applications
Many real-time systems are now being used in safety-critical applications, in which human lives or expensive machinery may be at stake. As real-time systems continue to evolve, their applications become more complex, and often require timely and predictable access to massive amounts of data. This need for advanced data management functionalities in real-time systems poses formidable intellectua...
