Concurrency Control in Database Systems
Ideas that are used in the design, development, and performance of concurrency control mechanisms have been summarized. The locking, time-stamp, optimistic-based mechanisms are included. The ideas of validation in optimistic approach are presented in some detail. The degree of concurrency and classes of serializability for various algorithms have been presented. Questions that relate arrival ra...

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 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 کاملA Survey of Concurrency Control Algorithms in the Operating Systems
Concurrency control is one of the important problems in operation systems. Various studies have been reported to present different algorithms to address this problem, although a few attempts have been made to represent an overall view of the characteristics of these algorithms and comparison of their capabilities to each other. This paper presents a survey of the current methods for controlling...
