WEB Services Integration with Distributed Applications
distributed application, web service, SAP, protocols, security
A Web service is a distributed application component. Web services distributed computing model allows application-to-application communication. There is nothing fundamentally new about the basic concept and the related technologies. The innovative thing about this is the reach of Web services and its ubiquitous support by literally all major vendors. Most likely, heterogeneity will at the end no longer be an obstruction for distributed applications. This paper describes the concept of service-oriented architecture (SOA) in conjunction with the Web services technology and covers the core Web services specifications which form a powerful and robust foundation for building distributed systems. It is presented a case study regarding the integration of the Web services with the SAP system for handling interoperability issues. The conclusions and the future proposed developments are presented in the end of the paper.
