Here, the service analysis intersected symbol is used to
denote two overlapping service clusters??”banking accounts and investment accounts.
More Detailed Analysis Proposition. Exhibit 13.15 does not provide adequate detail to construct
a logical composition diagram. It merely represents a high-level cluster intersection operation.
Therefore, Exhibit 13.16 is an expanded version. It reveals the three major parties that take part
in the analysis proposition diagram: (1) services that reside in the investment accounts and the
banking accounts intersected clusters, (2) services that are positioned in the overlapped section,
and (3) banking accounts division and investment accounts division domains that the clusters are
integrated with. Consider the following analysis proposition details:
??? The banking accounts service cluster aggregates three services that use the analysis aggregation
notation: checking account (atomic), savings account (composite), and banking
account management (atomic). Note that there is no containment relationship between
these three services.
??? The investment accounts service clusters are composed of the atomic services trading
account, equity trading account, and fixed-income account. Note that there is no aggregation
relationship between these services.
??? The banking accounts and the investment accounts clusters are integrated with the banking
and investment accounts divisions??™ business domains.
