Server Push

Nowadays Web services are one of the most commonly used technologies for distributed system integration and interoperability. Recently, a new communication technique called WebSockets has appeared for implementing Web services that offer a true server-push mechanism. In this paper we present a system based on it to manage agent communications, and we motivate its use in an Assistive Technologies use case. A new WebSocket Message Transport Protocol is described and an implementation for the Jade platform is presented. Subscription based agent interaction for the use case is presented, along with a comparison between WebSocket and HTTP Message Transport Protocols.

The Cost

The modern B2B electronic business system should be able to make the enterprise meet better the need of the market, which must have some characteristics of cross-organization, cross-enterprises and frequent interaction. The paper proposes a dynamic electronic commerce model based on XML and Web Services, which consists of presentation layer, Web Services layer, application service layer, data integration layer and data layer. The dynamic e-business model can not only implement the loose system integration, but also be able to reuse the existing resources, and reduce to the cost of system integration and implementation time.

Information System Integration

The first task in health information system integration is to solve the problems of an “isolated information islands” and achieve the information and resource sharing. Some health information system integration technologies based on SOA and web services is researched. A prototype system of health information system integration based on SOA and web service is put forward. An integrated client, which employs the data redirection techniques in operating systems and is called the universal health information integration component, is developed. A real case study is used to show the design and implementation details as well as the valid integration among the heterogeneous system we have obtained.

Service-Oriented Computing (SOC) has recently gained attention both within industry and academia; however, its characteristics cannot be easily solved using existing distributed computing technologies. Composition and interaction issues have been the central concerns, because SOC applications are composed of heterogeneous and distributed processes. To tackle the complexity of inter-organizational service integration, the authors propose a methodology to decompose complex process requirements into different types of flows, such as control, data, exception, and security. The subset of each type of flow necessary for the interactions with each partner can be determined in each service. These subsets collectively constitute a process view, based on which interactions can be systematically designed and managed for system integration through service composition. The authors illustrate how the proposed SOC middleware, named FlowEngine, implements and manages these flows with contemporary Web services technologies. An experimental case study in an e-governmental environment further demonstrates how the methodology can facilitate the design of complex inter-organizational processes.
