Designing a service-oriented application requires
developers to define related well documented interfaces for all
conceptual services identified by the analysis phase prior
to constructing them. The service design phase encompasses the steps of
singular service specification, business process specification, and policy specification for both
singular services as well as business processes. Service design is
based on a twin- track design approach that provides two production
lines one along the logical part and one along the physical part of the
SOA abstraction layers. The purpose of logical service design is to
define singular services and assemble (compose) services out of
reusable singular service constellations. This calls for a business process
model that forces developers to determine how services combine and
interact jointly to produce higher level services. The physical design
trajectory focuses on how to design component implementations that
implement services at an acceptable level of granularity. Physical
design is based on techniques for leveraging legacy applications and
component-based development techniques. [Papazoglou 2007] |
