<p>A method for executing a task to be carried out by one or more computer systems through a workflow scheme representing said task, wherein said task is represented by a set of workflow items, each workflow item representing an action, each workflow item receiving one or more inputs from other workflow items and delivering one or more outputs to other workflow items, thereby forming a workflow representation of said task, said method comprising: identifying a workflow item delivering as an output the desired result of said task; tracing the workflow representation to identify all other workflow items which directly or indirectly deliver an output necessary to have a complete input for said selected workflow item; and carrying out the actions corresponding to all identified workflow items to thereby carry out the computational task. <IMAGE></p> |
