Dynamic Projection from Choreography to Orchestration Based on Role Correlation

For guaranteeing the right design of SOA(Service-oriented Architecture), it is the critical step that the transfer from Choreography to Orchestration. This paper present a new mapping algorithm from Choreography to Orchestration based on role correlation, which right fits the projection granularity, deduces the complexity of generated Orchestration, therefore, development, maintenance, and adaptability would be greatly improved. Our algorithm is based on both business experience stat data and the role correlation within a participant in the Choreography.
