Abstract

In service-oriented architecture, a web service evolves over time. Changes in a service may affect the quality of service for the service provider as well as for the service consumer. The quality of a service is measured from its structural perspective and therefore the proposed metrics are defined considering the web service description language document of a service. In this paper, a suite of metrics consisting of service evolution metric, service client-code evolution metric and service usefulness evolution metric has been proposed which measures service evolution for the service provider, impact of service evolution on the client code and on the usefulness for the service consumer. The time complexity of the proposed metrics is linear. The study of correlation between these metrics is conducted which indicates to the service provider whether the changes made in the service have tangible benefits for the consumer. To show the applicability of the metrics, real world data as well as simulated data has been used. Zuse framework has been used to theoretically validate the metrics. All the metrics are above the ordinal scale.
