Workflow management with BPEL
All Together

BPEL helps you build tools for managing workflows.
An employee who is going on a business trip mails the dates and target location to a service center; somebody in the back office copies these details to various online booking portals and issues a confirmation memo. The employee then returns from the trip and enters the same data again for an expenses claim. Some clever employee might use scripting to automate this process, thereby removing the need for entering redundant information, but what happens if the company modifies the process? Will anyone take the time to rewrite all the custom scripts?
Developers often need a way to modify business processes without reinventing the underlying infrastructure. The processes are thus the interface between the productive departments and IT. At the same time, developers and administrators need to keep track of the whole system and its internal processes – a challenge for both modelers and architects.
