Fig. 8.2.2 Big data contains repetitive data and nonrepetitive data.

The Nonrepetitive Raw Big Data/Existing Systems

Interface

The interface from the nonrepetitive raw big data environment is one that is very
different from the repetitive raw big data interface. The first major difference is in the
percentage of data that are collected. Whereas in the repetitive raw big data interface,
only a small percentage of the data are selected, in the nonrepetitive raw big data

interface, the majority of the data are selected. This is because there is business value in
the majority of the data found in the nonrepetitive raw big data environment, whereas
there is little business value in the majority of the repetitive big data environment.

But there are other major differences as well.

The second major difference in the environments is in terms of context. In the repetitive
raw big data environment, context is usually obvious and easy to find. In the
nonrepetitive raw big data environment, context is not obvious at all and is not easy to
