Chapter 1.7: A Brief History of Data

Big Data

But volumes of data continued to increase. Soon, there were systems that went beyond
the capacity of even the largest parallel database. A new technology known as big data
evolved in which the optimization of the data management software was on the volumes
of data to be managed, not on the ability to access data in an online manner.

Fig. 1.7.10 depicts the arrival of big data.

With big data came the advent of the ability to capture and store an almost unlimited
amount of data. The arrival of the ability to handle massive amounts of data brought with
it the need for a completely new infrastructure.

The Great Divide

And with the recognition of the need for a new infrastructure came the recognition that
there were two distinctly different types of big data. There is repetitive big data, and
there is nonrepetitive big data. And both repetitive big data and nonrepetitive big data
required dramatically different infrastructure.

Fig. 1.7.11 shows the recognition of the difference between repetitive big data and
