Fig. 16.1.1 A typical order in which the end state architecture is built.The first part of the end-state architecture to be built is the applications. After the
applications have matured and the siloed effect of the applications is noticed, a corporate
data warehouse is built. The corporate data warehouse integrates the application data and
provides a place for historical data to gather. After the data warehouse is built, the
different data marts begin to spring up.
Data start to accumulate in the data warehouse. Then after a while, the data lake/big data
environment is built. The data lake/big data environment is also used to collect data from
external and extraneous sources.
