Resolving Impassiveness in Service Oriented Architecture

In a Service Oriented Architecture, service registry called UDDI (Universal Description Discovery & Integration) is used as a database that includes description of published services. UDDI has an important defect called impassiveness that means the lack of consumer interaction with UDDI after he/she found some desired service. This means that consumers are not notified when some deletion or change of a service happens in UDDI. This paper aims to deal with resolving the problem of UDDI impassiveness by means of techniques of active database rules. To this end, we present new architecture for UDDI. In addition, the proposed architecture puts Web service invocation with toleration and includes the consumer classification.
