Typically data warehouses and marts contain normalized data gathered from a variety of sources and assembled to facilitate analysis of the business.
Big data architecture stack layers in order.
The security requirements have to be closely aligned to specific business needs.
This is the stack.
As you see in the preceding diagram big data architecture or unified architecture is comprised of several layers and provides a way to organize various components representing unique functions to.
Towards a generalized big data technology stack.
The data warehouse layer 4 of the big data stack and its companion the data mart have long been the primary techniques that organizations use to optimize data to help decision makers.
Security layer this will span all three layers and ensures protection of key corporate data as well as to monitor manage and orchestrate quick scaling on an ongoing basis.
Some unique challenges arise when big data becomes part of the strategy.
New big data solutions will have to cohabitate with any existing data discovery tools along with the newer analytics applications to the full value from data.
We propose a broader view on big data architecture not centered around a specific technology.
How do organizations today build an infrastructure to support storing ingesting processing and analyzing huge quantities of data.
Security and privacy requirements layer 1 of the big data stack are similar to the requirements for conventional data environments.
