Service-Oriented Analysis

Description

Download Course Sample

Service-Orientation holds the promise of delivering on the hope of every business: a software foundation that is immediately adaptable to changes in business model and business needs. Adopting a service-oriented architecture enables the technical infrastructure, but that is really the easier part. The greater challenge is identifying those business services to be supported with that infrastructure. This 2-day course is devoted to practical techniques for identifying and describing the right business services to be implemented within a service-oriented architecture. Exercises in each section of the course demonstrate techniques to identify candidate services, then challenge them to identify “actual” services. The various types of services are discussed, and emphasis is placed on identifying the responsibility profile of each service - a proven technique to eliminate duplication of functionality. Further exercises demonstrate how to define the interactions and operations of each service to assure it meets its prescribed business goals.

At the end of this course, the student will be able to:

Explain the concepts of Service-Orientation, and the goals of SO-Analysis
Follow a practical process for identifying business services
Use several approaches to identify candidate services
Organize candidate services to produce a service granularity hierarchy
Apply six refactoring techniques to eliminate service redundancy and overlap
Effectively challenge candidate services to identify the set of real services
Document service responsibilities for use, and reuse
Identify service operations and interactions
