Abstract Views: 0

The exponential growth of digital health data has introduced new challenges in storage, management, and security. Data Warehousing (DW) and Blockchain have emerged as two key paradigms to address these issues. DW provides structured, analytical capabilities for decision support, while Blockchain ensures decentralized trust and immutability. This paper presents a comparative analysis of DW and Blockchain in healthcare, focusing on security, interoperability, and transparency. A novel Explainability Layer is integrated to enhance interpretability and auditability of blockchain-based systems. A comparative experiment evaluates both technologies under identical workloads, highlighting Blockchain’s superiority in traceability and DW’s efficiency in query performance. Finally, a future-facing discussion identifies emerging hybrid architectures that blend DW performance with Blockchain transparency.
