Each standard and protocol execute a function and inside possessed a distinct job of the architecture Web Services. In summary, it can be affirmed that the exchange of data between the supplier and the consumer of the Web Service is carried through through protocol SOAP. The services are described using language WSDL. The publication process, searches and discovery WS is carried through by the UDDI. Finally, the HTTP is defined as used protocol more as transport canal. In the stack of protocols and standards Web Services it is distinguished language XML.
Standard is about the language used in this context for transference of information between the applications. It is through it that systems you go off obtain to communicate between itself, of flexible and dynamic form. (IT HISSES, 2001). The XML reveals widely executable and easy of being developed, being considered of great importance in the Internet and great intranets, therefore to provide interoperao with computers. With it, applications can be constructed and be brought up to date more quickly, allowing multiple platforms of visualization of the structuralized data. (IT WOULD MAKE, 2005). According to Jorgensen (2002), the XML is quickly if becoming the universal protocol for transference of information. The trend is that it is each time more used to transmit, to change and to manipulate given.
Aiming at to strengthen the study of the thematic one, an interesting example of an application that uses Web Services and XML, it would be the communication between systems of the securitrio environment. Where, for commercialization of insurances it is necessary integration between different systems. In ample direction, the study of the technology Web Services and XML they possess great relevance to the market of distributed applications, is considered the ideal solution for integration of systems. Its base formed for protocols and formats of data standards favor the communication between resident systems in multiple platforms, with distinct models of objects and different programming languages.
