Research ArticleOpen accessIn the keywordsOn Optimistic Concurrency Control for Real-Time Database SystemsAmer A. AliThe performance of database transaction processing system can be profoundly affected by the concurrency control method employed since it is necessary to preserve database integrity in a multi-user environment. In addition to satisfying the consistency requirement as in traditional database system, real-time database systems must also satisfy timing constraints. In this study we present a virtual run policy for the … …American Journal of Applied Sciences, Vol. 3, Issue 2 · 28 Feb 2006 · 6,901 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsability Assessment of E-Commerce Systems Using McCall’s Quality ModelSiti Solehah Othman, A Noraziah, Roslina Mohd SidekE-commerce platforms rely fundamentally on business database transaction systems that must balance user experience with security and data integrity. Traditional usability assessment methodologies often overlook critical security elements and transactional integrity requirements. This study employs McCall's Quality Model to comprehensively evaluate the usability characteristics of three prominent e-commerce platforms: Temu, Shopee, and Lazada. Through structured task-based evaluations and Likert-scale questionnaires, … …Journal of Computer Science, Vol. 21, Issue 11 · 19 Dec 2025 · 2,541 accessesView PDFCite
Research ArticleOpen accessIn the abstractComplex SQL-NoSQL Query Translation for Data Lake ManagementNurhadi, Rabiah Abdul Kadir, Ely Salwana Mat SurinA data lake refers to an extremely large data resource or repository. Data lakes store large amounts of data and use advanced analytics to pair data from multiple sources with different types of structured, semi-structured, and unstructured information. NoSQL databases such as Mongodb, Redis, Neo4j, and Cassandra are nontabular and they store data differently rather than use relational tables. NoSQL … …Journal of Computer Science, Vol. 18, Issue 12 · 19 Dec 2022 · 9,277 accessesView PDFCite
Research ArticleOpen accessIn the abstractIs Single Scan based Restructuring Always a Suitable Approach to Handle Incremental Frequent Pattern Mining?Shafiul Alom Ahmed, Bhabesh NathIncremental mining of frequent patterns has attracted the attention of researchers in the last two decades. The researchers have explored the frequent pattern mining from incremental database problems by considering that the complete database to be processed can be accommodated in systems’ main memory even after the database gets updated very frequently. The FP-tree-based approaches were able to draw more … …Journal of Computer Science, Vol. 17, Issue 3 · 12 Mar 2021 · 6,923 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuery Tuning in Oracle DatabaseNofri Alhadi, Kamsuriah AhmadOracle database is well suited to use for managing and exchanging of corporate data, especially for companies that have large-scale databases. Even though Oracle can work best, however, there are conditions where Oracle does not perform well and consume more time to perform the query transaction. This is when the database tuning process is needed. This process will solve the … …Journal of Computer Science, Vol. 8, Issue 11 · 5 Nov 2012 · 7,319 accessesView PDFCite
Research ArticleOpen accessIn the abstractHandling Fragmented Database Replication through Binary Vote Assignment Grid QuorumAinul Azila Che Fauzi, A. Noraziah, Noriyani Mohd Zain et al.Problem statement: Organizations critically needed to supply recent data to users who may be geographically remote, while at the same time handle a volume request of distributed data around multiple sites. The storage, availability and consistency are important issues to be addressed in order to allow distributed users efficiently and safely access data from many different sites. Approach: Data replication … …Journal of Computer Science, Vol. 7, Issue 9 · 23 Jul 2011 · 7,200 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving Response Time of Authorization Process of Credit Card System Using Multi-Threading and Shared-Memory Pool TechniquesSiti H.A. Hamid, Mohd H.N.M. Nasir, Wong Y. Ming, Hazrina HassanCurrent credit card authorization was developed on single-threaded model whereby authentication process takes longer time to respond due to sequential process of card's risk management profile and its limitation of handling huge number of simultaneous transactions at single point of time. As a result, the performance of the authorization system was affected during peak hours. This study presented an architectural … …Journal of Computer Science, Vol. 4, Issue 2 · 28 Feb 2008 · 7,236 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Secure Time-Stamp Based Concurrency Control Protocol For Distributed DatabasesShashi Bhushan, R. B. Patel, Mayank DaveIn distributed database systems the global database is partitioned into a collection of local databases stored at different sites. In this era of growing technology and fast communication media, security has an important role to play. In this paper we presented a secure concurrency control protocol (SCCP) based on the timestamp ordering, which provides concurrency control and maintains security. We … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,885 accessesView PDFCite
Research ArticleOpen accessIn the abstractReal-time Optimistic Concurrency Control based on Transaction Finish DegreeHan Qilong, Hao ZhongxiaoConcurrency control is one of the main issues in the studies of real-time database systems. Optimistic concurrency control algorithms have the attractive properties of being non-blocking and deadlock-free. However, they have the problems of late conflict detection and transaction restarts. Although the number of transaction restarts is reduced by dynamic adjustment of serialization order in real-time database systems, they are … …Journal of Computer Science, Vol. 1, Issue 4 · 31 Dec 2005 · 6,688 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordIMPROVING DATA AVAILABILITY IN MOBILE ENVIRONMENT USING DATA ALLOCATIONMoaiad Ahmad Khder, Zulaiha Ali Othman, Abdullah Mohd Zin, Salha AbdullahData distribution is one of the crucial issues in Data Base Management Systems (DBMS) in general and in Mobile environment in Particular. It is important because, if not properly managed, it will cause reduction in data availability, which in turn causes more rejections in transactions. Replication algorithms (e.g., CCM) are used to improve data availability. However, the database replication algorithms … …Journal of Computer Science, Vol. 9, Issue 8 · 5 Jul 2013 · 6,860 accessesView PDFCite
