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

arXiv.org, 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.

Hyperledger Fabric Graph Isomorphism Network for Conflict Transactions Detection in Multi-Version Concurrency Control

IEEE Access
Multi-Version Concurrency Control (MVCC) is a critical mechanism in blockchain systems such as Hyperledger Fabric. MVCC is crucial for managing concurrent transactions ensuring integrity through versioning and timestamp techniques.

Model-Based Proactive Read-Validation in Transaction Processing Systems [PDF]

, 2018
Concurrency control protocols based on read-validation schemes allow transactions which are doomed to abort to still run until a subsequent validation check reveals them as invalid.

Prompt Application-Transparent Transaction Revalidation in Software Transactional Memory [PDF]

, 2017
Software Transactional Memory (STM) allows encapsulating shared-data accesses within transactions, executed with atomicity and isolation guarantees. The assessment of the consistency of a running transaction is performed by the STM layer at specific ...

Concurrence control for transactions with priorities [PDF]

, 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

Scalable XML Collaborative Editing with Undo short paper [PDF]

, 2010
Commutative Replicated Data-Type (CRDT) is a new class of algorithms that ensures scalable consistency of replicated data. It has been successfully applied to collaborative editing of texts without complex concurrency control. In this paper, we present a

Change Mining in Adaptive Process Management Systems [PDF]

, 2006
The wide-spread adoption of process-aware information systems has resulted in a bulk of computerized information about real-world processes. This data can be utilized for process performance analysis as well as for process improvement.

Modular Synchronization in Multiversion Databases: Version Control and Concurrency Control [PDF]

, 1989
In this paper we propose a version control mechanism that enhances the modularity and extensibility of multiversion concurrency control algorithms. We decouple the multiversion algorithms into two components: version control and concurrency control. This

Superdatabases for Composition of Heterogeneous Databases [PDF]

, 1986
Superdatabases are designed to compose and extend databases. In particular, superdatabases allow consistent update across heterogeneous databases. The key idea of superdatabase is hierarchical composition of element databases.
