Gundla, Venkat Mounish (2025) Demystifying data engineering for AI in Healthcare: A strategic beginner’s guide. World Journal of Advanced Engineering Technology and Sciences, 15 (2). pp. 819-827. ISSN 2582-8266

The integration of artificial intelligence into healthcare represents a transformative force with potential to revolutionize patient care, operational efficiency, and clinical outcomes. Data engineering forms the indispensable foundation of this revolution, yet remains poorly understood by many healthcare stakeholders. This introduction to data engineering in AI-powered healthcare illuminates the complex ecosystem of data pipelines, architectures, and quality frameworks essential for successful implementation. Healthcare generates extraordinarily diverse data across structured, semi-structured, and unstructured formats, presenting unique challenges including interoperability barriers, quality inconsistencies, and stringent privacy requirements. The relationship between data quality and AI effectiveness demonstrates fundamental importance - model performance correlates substantially more strongly with data quality than algorithm sophistication. Modern healthcare data architectures have evolved dramatically from traditional silos to sophisticated data mesh approaches, enabling substantially improved analytical capabilities with reduced latency and maintenance costs. Cloud adoption has further transformed implementation strategies, with hybrid architectures predominating. Different healthcare AI applications demand specialized architectural patterns optimized for specific use cases ranging from real-time monitoring to population health analytics and precision medicine. Understanding these foundational data engineering concepts enables healthcare professionals to better navigate the intersection of data infrastructure and AI applications.
