layered domain structure??“known as a parent domain. Exhibit 11.4 exemplifies a three-layer business
structure. On the very bottom is the loan processing business domain (the parent layer),
denoted by the characters D1.L1. Right above this level is the risk assessment domain (D2.L2),
and the very top business layer is identified as the credit verification domain (L3.L3). This
hierarchical formation represents the loan-issuing operation of a financial organization.
To further formalize this presentation, employ the service-oriented business integration
notation using the contained integration symbol to construct a business domain layered structure,
which is shown in Exhibit 11.5. This illustration depicts a formal business integration modeling
diagram in which the bottom business domain D1.L1 serves as the base layer containing the
other two domains, D2.L2 and D3.L3, which are piled on top of each other. Note that the
???contained??? symbol conveys their internal associations and their business dependencies.
