Visualizing Concurrency Control Algorithms for Real-Time Database Systems

open access: yesData Science Journal, 2008
This paper describes an approach to visualizing concurrency control (CC) algorithms for real-time database systems (RTDBs). This approach is based on the principle of software visualization, which has been applied in related fields.

Concurrency Control in Database Systems

open access: yesIEEE Transactions on Knowledge and Data Engineering, 2019
Concurrency control mechanisms including the wait, time-stamp and rollback mechanisms have been briefly discussed. The concepts of validation in optimistic approach are summarized in a detailed view.

A Concurrency Control Method Based on Commitment Ordering in Mobile Databases [PDF]

open access: yes, 2011
Disconnection of mobile clients from server, in an unclear time and for an unknown duration, due to mobility of mobile clients, is the most important challenges for concurrency control in mobile database with client-server model.

Contextual concurrency control [PDF]

open access: yesProceedings of the Workshop on Hot Topics in Operating Systems, 2021
Kernel synchronization primitives are of paramount importance to achieving good performance and scalability for applications. However, they are usually invisible and out of the reach of application developers. Instead, kernel developers and synchronization experts make all the decisions regarding kernel lock design. In this paper, we propose contextual

Transactional concurrency control for intermittent, energy-harvesting computing systems

open access: yesACM-SIGPLAN Symposium on Programming Language Design and Implementation, 2019
Batteryless energy-harvesting devices are computing platforms that operate in environments where batteries are not viable for energy storage. Energy-harvesting devices operate intermittently, only as energy is available.

Real-time Index Concurrency Control [PDF]

open access: yesIEEE Transactions on Knowledge and Data Engineering, 1996
Real time database systems are expected to rely heavily on indexes to speed up data access and thereby help more transactions meet their deadlines. Accordingly, high performance index concurrency control (ICC) protocols are required to prevent contention for the index from becoming a bottleneck.

Concurrence control for transactions with priorities [PDF]

open access: yes, 1989
Priority inversion occurs when a process is delayed by the actions of another process with less priority. With atomic transactions, the concurrency control mechanism can cause delays, and without taking priorities into account can be a source of priority

Concurrency control [PDF]

open access: yesACM Computing Surveys, 1998
Standard locking (two-phase locking with on-demand lock requests and blocking upon lock conflict) is the primary concurrency control (CC) method for centralized databases. The main source of performance degradation with standard locking is blocking, whereas transaction (txn) restarts to resolve deadlocks have a secondary effect on performance.
