Clearly, a significant challenge in the
process of governing big data is categorizing, modeling and mapping the
data as they are captured and stored, particularly because of the unstructured
nature of much of the information. Data often come from external sources,
and accuracy cannot always be easily validated; also, the meaning and
context of text data are not necessarily self-evident. For many enterprises,
big data involves a collective learning curve for all concerned: IT managers,
programmers, data architects, data modelers and data governance professionals.
