The Data Infrastructure

Abstract

Corporate data include everything found in the corporation in the way of data. The most
basic division of corporate data is by structured data and unstructured data. As a rule,
there are much more unstructured data than structured data. Unstructured data have two
basic divisions—repetitive data and nonrepetitive data. Big data is made up of

unstructured data. Nonrepetitive big data has a fundamentally different form than
repetitive unstructured big data. In fact, the differences between nonrepetitive big data
and repetitive big data are so large that they can be called the boundaries of the “great
divide.” The divide is so large; many professionals are not even aware that there is this
divide. As a rule, nonrepetitive big data has MUCH greater business value than repetitive
big data.

If there is any secret to data management and data architecture, it is understanding data
in terms of its infrastructure. Stated differently, trying to understand the larger
architecture under which data are managed and operate is almost impossible without
understanding the underlying infrastructure, which surrounds data. Therefore, we shall
spend some time understanding infrastructure.

Two Types of Repetitive Data

A good starting point for understanding infrastructure is to start with the observation that
there are two types of repetitive data found in corporate data. In the structured side of
corporate data, repetitive data are found. In the unstructured big data side of corporate
data, repetitive data are also found. Despite the fact that the types of data sound the
same, there are significant differences between the different types of repetitive data.
When it comes to structured repetitive data, it is normal to have transactions as part of
