Soa 5 service oriented analysis and design
- 1. Service Oriented Architecture:5 Service Oriented Analysis and Design Prof Neeraj Bhargava Vaibhav Khanna Department of Computer Science School of Engineering and Systems Sciences Maharshi Dayanand Saraswati University Ajmer
- 2. Service and Service Orientation What is a service? âą Discrete unit of functionality âą Autonomous âą Standardization âą Black box What is service orientation? âą Logic decomposed into smaller pieces âą Specific âą Software to solve individual concerns
- 3. How a service encapsulates logic âą Relationship between service and logic: âą 1.Serviceâtask in a process âą 2.Serviceâsub-process âą 3.Service-process
- 4. How services relate? âą Service awareness âą Service description âą Service communication
- 5. How services communicate âą Send messages âŠ.. Autonomous âŠ. Self governing logic Components of SOA âą ServicesâŠ.. Service description âą Messages
- 6. How are services designed âą What is processing logic? âą What is service oriented processing logic? âą What is service oriented solution
- 8. Operations âą Operations: Transactions that represent single logical units of work (LUWs). âą Execution of an operation will typically cause one or more persistent data records to be read, written, or modified. âą SOA operations are directly comparable to object- oriented (OO) methods. âą They have a specific, structured interface, and return structured responses. âą Just as for methods, the execution of a specific operation might involve invocation of additional operations.
- 9. Services âą Services: Represent logical groupings of operations. âą For example, if we view Customer Profiling as a service, then, Lookup customer by telephone number, List customers by name and postal code, and Save data for new customer represent the associated operations
- 10. Business Processes âą Business Processes: A long running set of actions or activities performed with specific business goals in mind. âą Business processes typically encompass multiple service invocations. âą Examples of business processes are: Initiate New Employee, Sell Products or Services, and Fulfill Order. âą In SOA terms, a business process consists of a series of operations which are executed in an ordered sequence according to a set of business rules
