One approach to developing service-oriented web applications is to transform high-level business models to a composition language that implements business processes with web services. Object-oriented analysis and design and UML-based diagrams are typically used in the software development process. In this paper, the authors propose using flow as a fundamental notion underlying understanding of activities in web services. They discuss the development of business processes through introduction of a conceptual model as a framework for design. They scrutinize current modeling used in transformation methodologies, and then introduce a flow-based conceptualization of services through case studies with a high-level business description.
