1.    One of the advantages of a Hadoop implementation is that it provides a high level of computing redundancy. Why is that particularly important in a healthcare setting? 2.    Explain how the three characteristics. of big data (volume, velocity, a. variety) apply to the data being collected by healthcare providers such as Mercy? 3.     How might Me, benefit from an enterprise data model, Does Mercy's move into big data make it more or less important that it have a clearly developed model that states the organizations' data n.ds and priorities?

Fundamentals of Datawarehouse

A data warehouse is a data repository which is used to store large quantities of historical data that are mostly used for creating reports that help businesses to identify their weaknesses and strengths. For example, demographics data about people of a region can help businesses identify the needs and preferences of the region’s population. A data warehouse acts as a central storage for storing data that comes from one or more heterogenous sources. It also consists of data which can be old and of historical value. One of the most important applications of this type of system is that it is used for supporting business intelligence and data analytics applications.
