The SOAP Protocol Used for Building and Testing Web Services

a web service represents a method by which applications can communicate with each other through asynchronous messages or calls on remote procedure (RPC -Remote Procedure Call). Therefore, we can say that a Web service is a software application that can be accessed remotely using XML-based language. Web services are just two programs that change data between them on the Internet or Intranet in XML format called SOAP (Simple Object Access Protocol). The moment that they have appeared, Web services have quickly become a useful component of the IT industry. Through them it was suggested the idea of structuring, modelling, organizing and describing information [14]. They have also become a central tool in applications that use the information exchange (B2B applications, distributed applications - client-server or peer to peer applications).
