A Service Framework and Coordinational Model in Embedded Workflow

Workflow can be embedded in various e-commerce systems, e.g. product lifecycle management(PLM) or supply chain management(SCM) etc. - to streamline the process management. By analyzing the application background, this paper proposed a low level formal service framework as an infrastructure to support the embedded workflow running. To decrease the coupling of these services, a coordinational model composed by event registration, event subscription and event notification was presented. Finally, as an illustration, an implementation method was given
