Understanding and creating zones within a data lake is the key to draining the swamp. Data lake zones form a structural governance to the assets in the data lake. These zones allow the logical and physical separation of data that keeps the environment secure, organized and agile. Zones are physically created through exclusive servers or clusters, or virtually created through the deliberate structuring of directories and access privileges.
Health care analytics architectures need a data lake to collect the sheer volume of raw data that comes in from the various transactional source systems used in health care such as electronic medical records, billing data, costing data, etc. Data then populates into various zones within the data lake. To effectively allocate resources for building and managing the data lake, it helps to define each zone, understand their relationships with one another, know the types of data stored in each zone and identify each zone’s typical user.

Data lakes are typically divided into four zones to make them work. Health care organizations may label these zones differently according to their preference, but their functions are essentially the same. Each specific zone is defined by the level of trust in the resident data, the data structure and future purpose and the user type.
Ultimately, a data lake helps health care organizations run their operations as a business. Real-time insights and predictive models mean fewer complications, fewer unnecessary emergency room interventions and higher levels of wellness across the population — all at a reduced cost.
