Remember, the relationship aspect of our service-oriented design,
discussed previously, does not address an overall view of all the services and consumers that participate
in a solution. Therefore, besides the service association discovery activity, it is also necessary
to represent the solution that is being proposed from a structural perspective. Specifically, this
effort pertains to building a logical formation, a design composition in which services are ???glued???
together to form a packaged structure that proposes a design modeling strategy. This approach
pertains to service reusability, loose coupling, and solutions to interoperability challenges.
Service Behavioral Modeling. The service-oriented design discipline advocates that we also
view a service and consumer interaction from a behavioral perspective; meaning the logical

design paradigm must also present business and technical functionality that services offer to their
subscribed consumers. Therefore, the design modeling discipline advocates that such a perspective
should be described by a transaction context. A transaction embodies service functionality, activities,
message coordination, and interaction. These aspects are managed by message orchestration
between service-oriented assets.
CONCEPTUAL AND LOGICAL ARCHITECTURE. What does it mean to architect a service-oriented
environment? What are the major activities advocated by the service architecture modeling discipline?
The service architecture process not only relies on conceptualization, analysis, business
integration, and design artifacts; it also combines all the deliverables to create a service and
consumer community.
