本文从岩心图像扫描及综合分析管理系统的实际应用背景出发,针对其存在的问题, 提出了基于Web Service(web 服务)的系统应用集成解决方案。通过对Web Services 的技术特点,体系结构及其关键技术的讨论,设计了基于Web Service 的分布式岩心图像扫描及综合分析管理系统应用集成模型,并利用.NET 技术,VC++和C#编程语言进行了系统应用集成的实现。 关键词: Web 服务;分布式系统;系统集成;可扩展标记性语言;简单对像访问协议 Abstract: A novel method set out from actual application background of the core image compositive analysis management system to implement the application integration of the system was presented,It was based on web service. Web services is a service-oriented architecture with the specific features of co-operation regardless of the platforms. A discussion to the architecture and the kernel techniques of web services is given,a model of the distributed core image compositive analysis management syste application integration was desianed and implemented by using .NET technology, C# programme language.
