However, as Web services evolve in adynamic environment which is the Internet many changes can occur and affect them. A Web service isaffected when one or more of its associated information sources is affected by schema changes.Changes can alter the information sources contents but also their schemas which may render Web servicespartially or totally undefined. In this paper, we propose a solution for integrating information sources intoWeb services. Then we tackle the Web service synchronization problem by substituting the affectedinformation sources.
