Web services composition, execution and visualization

This work presents a technique and a tool for Web service composition, execution and visualization. Web services composition refers to the act of interconnecting multiple elementary (or other composite) Web services, in order to create value-added functionality for customers. Graphical tools allow developers to define and create business processes on a "plug and play" basis. Runtime visualization of a business process enables the developers to understand the process and if necessary intervene in the process.
