DRDB: a distributed real-time database server for high-assurance time-critical applications

چکیده
Many real-time database systems are now being used in safety-critical applications, in which human lives or expensive machinery may be at stake. Transactions in real-time databases should be scheduled considering both data consistency and timing constraints. In addition, a real-time database must adapt to changes in the operating environment and guarantee the completion of critical tasks. The effects of scheduling decisions and concurrency control mechanisms for real-time database systems have typically been demonstrated in a simulated environment. In this paper we present a functional realtime database servel; called DRDB, which provides an operational platform for research in distributed realtime database issues.

DRDB: 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...
متن کاملSeparating indexes from data: a distributed scheme for secure database outsourcing
Database outsourcing is an idea to eliminate the burden of database management from organizations. Since data is a critical asset of organizations, preserving its privacy from outside adversary and untrusted server should be warranted. In this paper, we present a distributed scheme based on storing shares of data on different servers and separating indexes from data on a distinct server. Shamir...

A Distributed Hard Real-Time Java System for High Mobility Components. (December 2004) Sangig Rho, B.S., Yonsei University; M.S., Yonsei University Chair of Advisory Committee: Dr. Riccardo Bettati In this work we propose a methodology for providing real-time capabilities to component-based, on-the-fly reconfigurable, distributed systems. In such systems, software components migrate across comp...
متن کاملComputer Network Time Synchronization using a Low Cost GPS Engine
Accurate and reliable time is necessary for financial and legal transactions, transportation, distribution systems, and many other applications. Time synchronization protocols such as NTP (the Network Time Protocol) have kept clocks of such applications synchronized to each other for many years. Nowadays there are many commercial GPS based NTP time server products at the market but they almost ...
متن کاملA Database Server for Distributed Real-Time Systems: Issues and Experiences
The design and implementation of database systems for real-time applications presents many new and challenging problems. In addition to maintaining data consistency, the database system must satisfy timing constraints associated with transactions. In this paper we present our experiences in integrating a database server with a real-time operating system kernel and our attempts at providing flex...
