associations that can affect the future technological environment. Exhibit 15.27 illustrates this
idea. The trading transaction processor, which is depicted as a workflow machine, uses the trading
hub offered services. This scenario implies that the transaction processor employs the trading
hub as a supporting intermediary for routing messages. In the same fashion, the trading hub
connecting machine uses the trading archive (depicted as a time machine) for saving the trading
transaction history. Remember, the recognized icon should not be used to illustrate message

COMBINED CONCEPTUAL ARCHITECTURE DIAGRAM. The final conceptual architecture model
diagram should include the various business, technology, and architectural concepts that focus
on the organizational solution to be resolved. This conceptual level modeling activity should
be driven by the vital technology abstractions discovered in the architecture conceptualization
phase. These concepts are the embodiment of a technological environment that is composed
of packaged solutions.
