Data Integrity and Security Mechanisms in Cloud-Based Relational Databases

Cloud-based relational databases have redefined how modern organizations store, manage, and scale data. While the cloud offers significant benefits in terms of accessibility and cost-effectiveness, it also introduces unique security and data integrity challenges. This paper examines the strategies and technologies used to safeguard data stored in cloud-hosted relational databases. We focus on critical concerns like data consistency, confidentiality, access control, and the protection of data from unauthorized alterations. Techniques such as cryptographic hashing, role-based access control (RBAC), and integrity verification mechanisms are discussed. The paper also highlights architectural best practices, outlines current challenges, and explores recent innovations such as blockchain and AI-driven anomaly detection
