Abstract

Different types of global information network services, used in the modern distributed software systems are described. Several approaches to service description and to service interaction are shown. Description of wide-spread and inculcated approaches to creation of distributed object interaction is given in the wide practice of the systems with spectrum of system and functional services. Web-service international standards stack (SOAP protocol, WSDL language, UDDI interface and service, XML, BPEL and BPMN notations, CORBA object broker and services, JEE application server) is briefly described. Models of web services, service-oriented approach (SOA), service-component architectures (SCA), and Windows Communication Foundation (WCF) service support application systems are considered for presentation of the business systems by the services ready to the decision of business-tasks. Features that support interoperability and multilanguage interaction are underlined. Principles of distributed software design (service composition, component engineering, interoperability, variance) that are of special care in SOA are listed. Some examples of presenting information using standard notations are given. An additional example of calculator service with functions of the data processing in ITK service-environment (WCF-based system) and the concept of web service implementation are presented.
