Databases, Workflows and the Grid in a Service Oriented Environment
[chapter]
2004
Lecture Notes in Computer Science
Preserved Fulltext
As the Grid moves towards adopting a service-oriented architecture built on Web services, coupling between processes will rely on secure, reliable, and transacted messages and be supported by databases ...
We have built a generic toolkit targeted at design engineers, which provides convenient methods to access a grid-enabled repository. ...
The toolkit enables engineers to write scripts in a familiar language and archive them along with data produced at various stages of the design optimisation process to a grid-enabled database. ...

We also discuss some of the challenges involved in maintaining program semantics, and show how the approach can be used for more ambitious optimisations in the future. ...
Also, it cannot detect indirect data dependencies -for example, if the RMI call modifies a remote database which the client proceeds to access using another API, then that access will go unnoticed. ...
