Abstract

A service re-factoring method and system. The method includes selecting by a computing system, a first service comprising a first name. The computing system receives a second name for a second service to be generated from the first service. The computing system executes a service refactoring software application, adjusts a granularity of the first service, and generates the second service. The computing system retrieves first traceability links associated with the first service and a first value associated with a first service identification technique. The first traceability links are created within the second service. The computing system generates a second value associated with a second service identification technique. The first service, the first name, and the first value are removed from the computing system. The computing system stores the second service, the second name, the second value, and the first traceability link.

2. The method of claim 1, wherein said first service comprises a coarse-grained candidate service, wherein said second service comprises fine-grained candidate services, wherein said generating said second service comprises re-factoring said coarse-grained candidate service into said fine-grained candidate services, and wherein said method further comprises:

processing, by said computing system, said second name.

3. The method of claim 1, wherein said first service comprises too-grained candidate services, wherein said second service comprises a fine-grained candidate service, wherein said generating said second service comprises re-factoring said too-grained candidate services into said fine-grained candidate service, and wherein said method further comprises:

processing, by said computing system, said second name.

4. The method of claim 1, wherein said first service comprises a coarse-grained exposed service, wherein said second service comprises fine-grained exposed services, wherein said generating said second service comprises re-factoring said coarse-grained exposed service into said fine-grained exposed services, and wherein said method further comprises:

processing, by said computing system, said second name.

5. The method of claim 4, further comprising:

retrieving, by said computing system, characteristics associated with said first service, wherein said characteristics are selected from the group consisting of service operations, parameters of service operations, service messages, service dependencies, service compositions, service non-functional requirements, associated business rules, realizing service components, and associated use cases of said first service; and

creating, by said computing system, said characteristics within said second service.

6. The method of claim 1, wherein said first service comprises too-grained exposed services, wherein said second service comprises fine-grained exposed service, wherein said generating said second service comprises re-factoring said too-grained exposed services into said fine-grained exposed service, and wherein said method further comprises:

processing, by said computing system, said second name.

7. The method of claim 6, further comprising:

retrieving, by said computing system, characteristics associated with said first service, wherein said characteristics are selected from the group consisting of service operations, parameters of service operations, service messages, service dependencies, service compositions, service non-functional requirements, associated business rules, realizing service components, and associated use cases of said first service; and

creating, by said computing system, said characteristics within said second service.

8. The method of claim 1, further comprising:

storing, by said computing system, said second service, said second name, said second value, and said second traceability link in said SOA project; and

executing, by said computing system, said SOA project.

9. The method of claim 1, wherein said service portfolio is retrieved from said SOA project.

10. A process for supporting computer infrastructure, said process comprising providing at least one support service for at least one of creating, integrating, hosting, maintaining, and deploying computer-readable code in said computing system, wherein the code in combination with said computing system is capable of performing the method of claim 1.

11. A computer program product, comprising a computer storage medium comprising a computer readable program code embodied therein, said computer readable program code configured to perform the method of claim 1 upon being executed by a processor of said computing system.

12. A computing system comprising a processor coupled to a computer-readable memory unit, said memory unit comprising instructions that when executed by the processor implements a service re-factoring method, said method comprising:

selecting, by said computing system from a service portfolio associated with a service oriented architecture (SOA) project in response to a command from a user, a first service comprising a first name for said first service;
