What are
these service affiliations about? Start with a thorough analysis of message exchange requirements
between the participating parties. These message paths that are being asked for simply pertain to
the various routes that consumers and services use to exchange information. Moreover, identifying
message passages and discovering access to services is not the only purpose of this exercise. It
is also necessary to protect services from being accessed by unnecessary operations and thus to
address their visibility aspects in aggregated structures such as composite services and service
clusters.
The logical design relationship process also accentuate the various implementation mechanisms
a practitioner can leverage to accommodate service-oriented mediation requirements.
Therefore, the roles of SOA intermediaries are vital to the design process. In addition, design
aspects such as service synchronization and cardinality are major topics that are being addressed
to enhance the service relationship analysis method.
SERVICE-ORIENTED LOGICAL DESIGN COMPOSITION STRUCTURE. The next step calls for
working with service structures to devise an overall composition of the design solution (described
in details in Chapter 13). This activity is not only about exploring collaborative behavioral aspects
of services. Here, the chief requirement is to formulate a service environment that is both contingent
on the service relationship discovered previously and depends on service structural formations
that drive service-oriented modeling strategies, such as service-oriented asset reuse, interoperability,
and loose coupling.
