Workflow assembly tool and workflow model for runtime execution

Abstract:

Techniques for generating a workflow model are described. In an example, a device presents a window. A selection of an icon presented in the window is received, where the icon corresponds to a node having a node type. Based on rule, the device determines a location where the icon can be added to a workflow. The rule indicates the location based on the node type and a workflow model. The user device presents, in the window, an indicator of the location, receives a placement of the node at the location, and presents, the icon at the location indicating that the node is added to the workflow. The device updates the workflow model to include, based on the placement, a reference to executable code that corresponds to the node, and to include, based on the location, information about an execution sequence of executable codes referenced in the workflow model.
