Developing End-User Programmable Service-Oriented Applications with VINCA

Raising end-user’s programmability is a promising way to ensure more flexible and higher-quality information provision and utilization, and to better cope with spontaneous business requirements as well. This paper presents the state-of-the-art developments of the end-user service composition language VINCA and its corresponding approach to developing end-user programmable applications on the basis of Service-Oriented Architecture. With VINCA, end-users can visually express (and later easily change) their personalized requirements from their business viewpoints, letting the underlying supporting environment take care of the technical details. The presented language and approach have been tried out with different real-world scenarios, and the evaluation in this regard is given in the paper.
