Designing A Data Warehouse for Healthcare Analytics Using Snowflake – To Store and Analyze Healthcare Analytics

Modern healthcare systems generate an overwhelming amount of data every day from electronic health records, billing systems, laboratory reports, and connected medical devices. Making sense of this data is essential for improving patient outcomes and supporting clinical and administrative decisions. However, many traditional on-premises data warehouses struggle to keep up due to limited scalability, high maintenance costs, and difficulties in managing data from multiple sources. Cloud-based solutions such as Snowflake have emerged as practical alternatives, offering flexible storage, scalable computing power, and easy integration with analytics and reporting tools. This review looks at how these platforms are currently used in healthcare data warehousing and discusses common approaches to data integration, performance management, and data security. It also points out the lack of unbiased, side-by-side comparisons between platforms and highlights the growing need for standardized practices, automation, and thorough evaluation methods to ensure their effective adoption in healthcare settings.
