The use of workflow technology within grid-based computing has received a lot of attention recently.Informally, a workflow is an abstract description of the steps or tasks required for executing a particular real-world process, and the flow of information between these tasks.Work passes through the flow from start to finish and activities might be executed by people or by system functions.Within a grid computing environment, a workflow provides the mechanisms for constructing distributed end user applications through the composition of distributed data services and computational services.Workflow systems typically enable users to construct their workflows using a visual interface and to submit them for execution by an execution engine that controls the invocation and data transfer between the different services.
