con:cern project is a workflow engine based on an extended case handling approach.
A process is described as a set of activities with pre- and postconditions. An activity is executed when its preconditions are met. It manipulates the process item, thereby creating postconditions. The process flow is determined at runtime. This approach is superior to the conventional process flow approach, especially if high flexibility and modularity are required.
Here are some key features of "con cern":
· complex process with exceptions and special cases
· execution sequence is dependent on multiple factors
· possibility of manual intervention of process flow
· content-based dependence amongst activities
· strong requirements to modularity
· strong requirements to flexibility
· loose process coupling
Interestingly, processes often turn out to be more complex than initially anticipated. con:cern's flexibility allows to restrict yourself to implementing the normal process flow. Special cases and exceptions can be manually dealt with at run-time, or can be gradually retrofitted.
When you can break systems down to pre conditions, post conditions, transfer functions, and the algorithms that implement them you can go a long way towards reliable systems and specs.
