Managing data dependencies in service compositions

Geert Monsieur, Monique Snoeck, Wilfried Lemahieu
2012 Journal of Systems and Software  
Composing services into service-based systems requires the design of coordination logic, which describes all service interactions realising the composition.  ...  The main goal of this article is to present an approach that deals with the design of coordination scenarios, to manage a set of data dependencies, whereas the data (and sequence) dependencies themselves  ...  Conclusion When services are composed into service-based systems, the design of a data flow is a crucial part of the service coordination.  ...

On the Concept of Service Coordination

Geert Monsieur, Monique Snoeck, Wilfried Lemahieu
2010 Social Science Research Network  
Data dependency There is a data dependency between a service s 1 and a service s 2 if the start or the continuation of the execution of service s 2 depends on data that is provided by s 1 .  ...  Even though this is a rather small example of data dependencies in a service composition, many coordination scenarios are possible.  ...
