Instructor: T. Pole
Agenda (for the week)
• Tonight, 4/20/09
– Ch 15: Service Oriented Design Part II Service Design
– Review Analysis and Design
• Chapters 11 through 15
• Wednesday, 4/22/09
– Example Project, Analysis and Design Templates
• Not complete artifacts, just outlines
– Reusable/Legacy Components, version 2
– Class Project Working Session
Ch 15: Service Oriented Design Part
III Service Design
• Overview of Goals and Strategy
• Goals
– Encapsulate the required logic
– Conform to service oriented principles
– Meet business requirements
• Strategy, order of steps
–
–
–
–
Design entity centric services
Design application services
Design task centric business oriented services
Design process services
• Control services, orchestrations and choreographies
• More details later in this lecture
Review Analysis and Design
• Chapters 11 through 15
– Service Oriented Analysis
– Service Modeling
– Service Oriented Architecture Composition
– Service Design
Service Oriented Analysis
• Primary questions:
– What services need to be built?
– What logic should be encapsulated by each service?
• Overall goals (i.e. steps or tasks):
– Define preliminary set of service OPERATION candidates
– Group operation candidates into logical contexts which are candidate
services
– SO Principles:
•
•
•
•
Identify reuse potential
Ensure contexts make sense (have a logical basis)
Identify issues that may impact service autonomy
Define known preliminary composition models
Service Modeling
• Model Candidate Services
– Decompose business processes
– Identify automatable process steps
• Also known as, filter out unsuitable steps
– Differentiate between process-agnostic and process-specific
logic
– Identify candidate service composition
– Identify, refine and finalize definition of service candidates
– Identify, refine and finalize definition of services compositions
Text Book: Service
Modeling Case Study
• 12.4 Contrasting service modeling approaches (an
example)
– Approach #1: Deriving hybrid services
– Approach #2: Deriving entity-centric services
– Approach #3: Mixing task-centric and entity-centric services
Service Oriented Architecture Composition
• Compose SOA
– Choose Service Layers
• Existing Services, SOA applications, etc.
• Enterprise Standards
• Composition Performance Considerations
– Position Core Standards
• Industry Standards
– Will you use UDDI?
– Choose SOA Extensions
• Which extensions will you use in which compositions?
Service Design
• Entity-Centric Business Service Design Process
– Establish the business service layer, fig 15-1
– Case study pp 503-521
• Application (Utiltiy) Service Design Process
– Establish the utility service layer, fig. 15-10
– Case study pp 524-538
• Task-Centric Business Service Design
– Complete the business service layer(s), fig. 15-15
– Case study pp 541-554
• Process (Control) Service Design
– Establish the control layer
– Chapter 16 – mostly but not completely beyond the scope of the class
