Short Essay: Data Lake   

The Data Lake approach to population health management allows health systems to collect, organize, combine, and normalize all types of data on an as-needed basis. Organizations that combine a data lake with massively parallel computing capabilities can quickly turn data from disparate sources into actionable information they can use to improve care.   

For this essay, research the following four types of data used for population health initiatives: administrative data; patient-generated data, clinical data, and claims data. In your short essay, discuss each type of data source, where it is derived from, and how it is used for population health initiatives.
