SOA Web Web SOA Web XML SOAP WSDL
SOA 和 Web 服务 —— Web 服务是 SOA 的关键促成者 • Web 服务 – 技术、产品和中间件无关 技术、产品和中间 – 采用 XML, SOAP, WSDL, UDDI 以 及 Web 服务扩充标准 • 基于 Web 服务的SOA UDDI Enables discovery of Binds to WSDL – 基于Web服务标准 – 提供互操作性 interoperability Is accessed using SOAP Enables Communication between Describes – 支持企业内部以及跨企业之间的集成 Web 服务
GIS标准和互操作性 GIS Standards and Interoperability
