Xstamps: a multiversion timestamps concurrency control protocol for XML data
Fourth International Conference on Information, Communications and Signal Processing, 2003 and the Fourth Pacific Rim Conference on Multimedia. Proceedings of the 2003 Joint, 2004 With the tremendous growth of XML data over the Web, efficient management of such data becomes a new challenge for database community. Several data management solutions, proposed in recent years, extend the capability of traditional database systems to meet the needs of XML data while alternative approaches introduce new generation databases, named as ...

Discrete Applied Mathematics, 1992 AbstractLet MC stand for a class of logs (i.e., sequences of read/write steps) that are serializable when multiple versions of the data items are maintained in the database. In this paper we propose a new type of multiversion cautions scheduler for database concurrency control, which dynamically imposes serialization constraints, consisting of all rw ...

Analysis of Real-Time Multiversion Concurrency Control Algorithms using Serialisability Graphs
International Journal of Computer Applications, 2010 This paper analyses the correctness of Multiversion Concurrency Control(MVCC) algorithms that are commonly deployed in Realtime Databases. Database systems for real-time applications must satisfy timing constraints associated with transactions. Typically, a timing constraint is expressed in the form of a deadline and is represented as a priority to be ...

Novel Big Data Networking Framework Using Multihoming Optimization for Distributed Stream Computing
Wireless Communications and Mobile Computing, Volume 2022, Issue 1, 2022., 2022 One of the main technologies for big data networking framework is online multihoming optimization that is large‐scale dimension table association technology in a distributed environment. It is often used in applications like real‐time suggestion and research. Big data is concerned with the quality of large datasets that are distributed.

Efficient Access Control Permission Decision Engine Based on Machine Learning
Security and Communication Networks, Volume 2021, Issue 1, 2021., 2021 Access control technology is critical to the safe and reliable operation of information systems. However, owing to the massive policy scale and number of access control entities in open distributed information systems, such as big data, the Internet of Things, and cloud computing, existing access control permission decision methods suffer from a ...

Dependence‐Cognizant Locking Improvement for the Main Memory Database Systems
Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021 The traditional lock manager (LM) seriously limits the transaction throughput of the main memory database systems (MMDB). In this paper, we introduce dependence‐cognizant locking (DCLP), an efficient improvement to the traditional LM, which dramatically reduces the locking space while offering efficiency.

Efficient Concurrent Execution of Smart Contracts in Blockchain Sharding
Security and Communication Networks, Volume 2021, Issue 1, 2021., 2021 Throughput performance is a critical issue in blockchain technology, especially in blockchain sharding systems. Although sharding proposals can improve transaction throughput by parallel processing, the essence of each shard is still a small blockchain.

Space and Time Bounded Multiversion Garbage Collection [PDF]
, 2021 We present a general technique for garbage collecting old versions for multiversion concurrency control that simultaneously achieves good time and space complexity. Our technique takes only $O(1)$ time on average to reclaim each version and maintains only a constant factor more versions than needed (plus an additive term).
