A scientific workflow system is a specialized form of a workflow management system designed specifically to compose and execute a series of computational or data manipulation steps, or workflow, in a scientific application. Scientific workflow systems are generally developed for use by scientists from different disciplines like astronomy, earth science, and bioinformatics. All such systems are based on an abstract representation of how a computation proceeds in the form of a directed graph, where each node represents a task to be executed and edges represent either data flow or execution dependencies between different tasks. Each system typically provides a visual front-end, allowing the user to build and modify complex applications with little or no programming expertise. Applications Distributed scientists can collaborate on conducting large scale scientific experiments and knowledge discovery applications using distributed systems of computing resources, data sets, and devices.

Workflow Management System
A workflow management system (WfMS or WFMS) provides an infrastructure for the set-up, performance, and monitoring of a defined sequence of tasks arranged as a workflow application. International standards There are several international standards-setting bodies in the field of workflow management: * Workflow Management Coalition * World Wide Web Consortium * Organization for the Advancement of Structured Information Standards * WS-BPEL 2.0 (integration-centric) and WS-BPEL4People (human task-centric), published by the OASIS Standards Body. The underlying theoretical basis of workflow management is the mathematical concept of a Petri net. Each of the workflow models has tasks (nodes) and dependencies between the nodes. Tasks are activated when the dependency conditions are fulfilled. Workflows for people WfMS allows the user to define different workflows for different types of jobs or processes. For example, in a manufacturing setting, a design document might be automatically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
