Service oriented specification and study of quality performance attribute

SOA enables integration of applications and resources flexibly, representing every application or resource as a service. It still suffer from no clear specifications to define this concept as the architectural style, and in particular, it has performance problem related to the creation of services that affect the total processing time of the system. We have defined more clearly SOA by providing a framework for this architecture, which allowed us to define the form of architectural style (components, connectors, services, etc.). Based on ADD, three architectural models have been well integrated into SOA. This is the breakdown of service (service breaks in basic services to facilitate reusability), the cache (to reduce the processing time of a service) and strategy (reduce processing time, easier maintainability, etc.). A case study is done to verify these tactics.
