Using techniques that are standard in data architecture, DOI identified those data subject areas 33 that needed to
be shared between business areas of the DOI enterprise. Figure 7-11 depicts one such example involving three
‘business focus areas’ and the citizen. Several information classes shown earlier are evident, for example:
� customer
� event 34

Common data and data sharing opportunities were also identified using identified data subject areas as a
unifying mechanism across COIs, as shown in Figure 7-12:

Logical data models were also developed according to business context, using the US Government’s Federal
Enterprise Architecture (FEA) BRM. Figure 7-13 is an example of one such logical data model:
33 A data subject area is comprised of one or more information classes.
