Scientific Workflow
These are networks of analytical steps that may involve, e.g., Database access and querying steps, data analysis and mining steps, and many other steps including computationally intensive jobs on high performance cluster computers.

Scientific Workflow
Workflow:“glue” heterogeneous data from multiple resources in efficient ways
Workflow management system (WMS) A Software that supports workflow modeling and execution

OSGi
OSGi:http://www.osgi.org/Main/HomePage
OSGi(open service gateway initiative) technology is Universal Middleware. OSGi technology provides a service-oriented, component-based environment for developers These capabilities greatly increase the value of a wide range of computers and devices that use the Java platform.
