The document discusses big data and analytics in healthcare. It notes that healthcare data is growing rapidly from a variety of sources like patients, providers, and payors. This data includes mostly unstructured clinical information. It also outlines some of the challenges in healthcare like technology limitations, data fragmentation, and lack of standards. The document proposes that big data solutions can help address these challenges by leveraging the volume, variety and velocity of healthcare data. This would help improve patient health through more effective communication and healthier lifestyle recommendations. It provides examples of logical and physical architectures for an enterprise data warehouse to store and process healthcare data at scale.
