The present invention relates to systems and methods for defining, implementing, deploying and/or executing Web services. A Web service is defined using a graphical interface that allows the application developer to specify the operation of the Web service through inclusion and configuration of graphical nodes representing particular operations and/or functions. The environment for definition typically includes a user input device, a graphical display device, a system data store and a system processor. The system processor is in communication with the other elements. A graphical definition of the Web service is stored in the system data store. Once defined, the graphical definition is convened into a programmatic implementation executable by a Web services server. This programmatic implementation can then be transmitted to an appropriate Web services server accessible by an intended user community.
