Development and Integration of Expert Systems Based on Service-Oriented Architecture

Service-Oriented Architecture (SOA) is one of the technologies under extensive discussion in recent years, and most noteworthy of all are Web Services. Web Services utilize core technologies, such as Extensible Markup Language (XML), Simple Object Access Protocol (SOAP), Web Services Description Language (WSDL) and Universal Description, Discovery, and Integration (UDDI), to construct an easy cross-heterogeneity platform, an information system that can be easily reused and expanded. Based on the SOA theory, the initial goal of this study is to develop a computer network problem diagnosis expert system for resolving frequently seen Web issues. Utilizing ASP.Net and SQL Server as the software tools, and based on Web Services, it provides for users a self-diagnostic computer network problem expert system and then utilizes this system to incorporate knowledge bases, expert systems, and conventional information systems developed in different development environments in order to expand the original system function and verify one of the most significant advantages of Web Services – communication between heterogeneous systems.
