CONCEPTUAL ARCHITECTURE ELEMENTS NOTATION. The conceptual architecture diagram
includes four major ingredients, each of which is represented by a unique symbol: business
domain, packaged technological asset, architectural concept, and technological function. These
icons are illustrated in Exhibit 15.20. Consider the following detailed description of each of the
participating elements in a conceptual model diagram.

Business Domain. Business organizations both sponsor projects and product construction and
own their empowering technologies. Remember that in the service-oriented business integration
phase, business domains were used that presented organizational lines of business, business products,
business structures such as departments and divisions, and even geographic locations. Thus,
this vital enterprise entity should play a major role in conceptual architecture modeling efforts,
as well. Note that the same domain symbol is used as in the service-oriented business integration
phase.
Packaged Technological Asset. The service-oriented conceptual architecture discipline advocates
that practitioners leverage technological packages that were devised in the service-oriented
design phase (Chapter 13) to establish technological abstractions.
