Extracting Services from Legacy for Service-Oriented Business Processes: Challenges and Issues
Youcef Baghdadi
Non-agile enterprises slowly adapts to changing business requirements, which could be harmful and affects their competitiveness. Their business processes are rigid and could not respond to the changes. One of the solutions is to use a service-oriented business modeling by stressing out role of SOA and Web services. In this modeling, business processes are represented by specialized services having separated concerns. These are (i) controller service, (ii) state service, and (iii) worker services. This solution requires an approach to: (1) map the existing services of the organization or its partners, or (2) reverse engineering techniques to provide business objects, represented in the information system, as a set of common, consistent service providers.
