the related summary data that can be stored in big data.
Fig. 9.2.10 shows this relationship of data inside big data.
Fig. 9.2.10 Detailed data can be summarized and stored in big data.But if detailed data and summary data should both be kept in big data and if detailed data
should not necessarily add up to the summary data found there, at the very least, there
should be documentation of the algorithm that was used to create the summary data.
Fig. 9.2.11 shows that documentation of algorithms and selection of detailed data should
be documented alongside the summary data stored in big data.
