Research ArticleOpen accessIn the keywordsUsability 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 keywordsA Design of MAC Model Based on the Separation of Duties and Data Coloring: DSDC-MACSoon-Book Lee, Yoo-Hwan Kim, Jin-Woo Kim, Chee-Yang SongAmong the access control methods for database security, there is Mandatory Access Control (MAC) model in which the security level is set to both the subject and the object to enhance the security control. Legacy MAC models have focused only on one thing, either confidentiality or integrity. Thus, it can cause collisions between security policies in supporting confidentiality and integrity … …Journal of Computer Science, Vol. 16, Issue 1 · 19 Jan 2020 · 7,459 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA New Database Encryption Model Based on Encryption ClassesKarim El Bouchti, Soumia Ziti, Fouzia Omary, Nassim KharmoumData encryption is one of the advanced measures used to consolidate data security inside Databases. It is an essential technique to protect data against theft, disclosure or modification from different typologies of attacks. In this work, we will propose a new database encryption model. It is based on a novel concept called "Encryption Classes". The proposed model is full compared … …Journal of Computer Science, Vol. 15, Issue 6 · 26 Jun 2019 · 7,705 accessesView PDFCite
