An Enterprise data hub uses a Hadoop platform as a central repository. This is next step in the evolution of data warehouses where instead of the traditional model where the data is extracted, transformed and loaded from one repository to the other, it is transformed in place inside an enterprise hub. The drivers for big data - volume, velocity and variety of data have driven this evolution in the data management model as well.
Most organizations are driving their data strategy around Hadoop which is becoming this central repository for all data. This allows for managing huge volumes of data, reduces the data preparation costs and helps the speed of reporting for analytics. There is a whole ecosystem of applications and data retrieval techniques that are being built around the enterprise hub.
