SOA
- 2. SERVICE-ORIENTED ANALYSIS The processs of determining how business automation requirements can be represented through service-orientation is the domain of the service-oriented analysis.
- 3. Objectives of service-oriented analysis The primary questions addressed during this phase are: -what services need to be built? -what logic should be encapsulated by each service?
- 4. The overall goals of performing a service-oriented analysis are as follows: • Define a preliminary set of service operation candidates. •Group service operation candidates into logical contexts. •Define preliminary service boundaries. •Identify encapsulated logic with reuse potential. •Define any known preliminary composition models. •Ensure that the context of encapsulated logic is appropriate for its intented use.
- 5. The service-oriented analysis process -The service-oriented analysis process is a sub-process of the overall SOA delivery life-cycle. -Service-oriented analysis can be applied at different levels, depending on on which of the SOA delivery strategies are used to produce services. -The chosen strategy will determine the layer of abstraction. -Each layer has different modeling requirements.
- 6. What outstanding work is needed to establish the required business model(s) and ontology? What modeling tools will be used to carry out the analysis? Will the analysis be part of an SOA transition plan? The questions that should be answered prior to proceeding with the service-oriented analysis include:
- 8. Step 1: Define business automation requirements Requirements are collected for analysis process. Creation of services in support of service-oriented solution. High-level automation process can be defined. Step 2: Identify existing automation systems SOA will not determine how exactly web service will encapsulate Web services relate to existing system are iorned out Step 3: Model candidate services Introduces the concept of service modeling Candidates are identified & grouped into into logic context
