Concurrency control in mobile distributed real-time database systems
With the rapid advances in mobile computing technology, there is an increasing demand for processing realtime transactions in a mobile environment. This paper studies concurrency control problem in mobile distributed real-time database systems (MDRTDBS). Based on the High Priority Two Phase Locking (HP-2PL) scheme, we propose a distributed real-time locking protocol, called Distributed High P...
متن کاملConcurrency Control in Real-Time Database Systems
Real-time systems (RTSs) form an important class of computer systems. They are characterized by existence of timing requirements concerning task execution times, and processing data items which values and validity change in time. We observe the growing importance of RTS applications which is accompanied with both the increase of data volumes processed by the systems and the requirements concern...
متن کاملLocking Based Concurrency Control for Integrated Real-Time Database Systems
In many database applications, incoming transactions are a mixed load of conventional (non real-time) and real-time (typically soft and rm) transactions. In this environment, transactions can even be changed dynamically from non real-time to soft or rm, or from soft to rm deadline transactions according to their execution paths. In this paper we show how lock based approach can handle these sit...
متن کاملConcurrency Control in Distributed Geographical Database Systems
This paper discusses concurrency control in distributed geographical database systems. A geographic data server providing transactional services must be designed to handle both longand short-duration transactions. The main challenges are identified as: (1) preserving the isolation property when concurrent transactions perform read and write operations on pages; (2) ensuring that search and othe...
متن کاملDistributed Concurrency Control in Real-time Cooperative Editing Systems
EEcient distributed concurrency control is one of the most signiicant challenges in building real-time cooperative editing systems. In this paper , we focus on the deenition and veriication of an integrated set of distributed concurrency control schemes based on a novel consistency model for solving three inconsistency problems: divergence, causality-violation, and intention-violation in real-t...
