Chapter 5.1: The Siloed Application Environment
Fig. 5.1.2 shows that there are multiple versions of the same data within different siloed
applications.

Fig. 5.1.2 Integrity of data—one of the problems with siloed data.

Not only do siloed applications have conflicting values of information, but also trying to
resolve the issues across the different applications is an intractable problem. There are a
multiplicity of reasons why the unbelievability of data across siloed applications presents
an intractable problem. But the single greatest reason for the intractability stems from the
fact that data cannot be meaningfully shared from one siloed application to the next.

Fig. 5.1.3 shows this issue.
