Based on research conducted by Kung-Kiu Lau and Cuong Tran that more than 70% of applications in the United Kingdom is still not integrated, so that ice information increase and data exchange between applications is inconsistent. To be able to exchange data between applications, each application should be able to provide services as a service provider to the other application as a service consumer, such as web service. Web service is a software system designed to support interoperability and interactions between systems on a network. Web service is used as a facility provided by a web to provide services in the form of information to other systems, so that other systems can interact with the system through a service provided by a system of web service providers. Data and information needs are often not only from one application, but can be derived from two or more applications. Integration two or more web services into one web service called composite web service. This research will implement a prototype composite web service, which is one web service that integrate three web services (web service hotel, car rental and tourism information) in one web service in a tourism case study.
