论文主要对内镜追溯系统进行论述，结合面向服务架构特点与实际系统需求设计出一种面向服务的数据中心 系统。系统采用.NET 平台的WCF 服务技术，HTTP 协议以及DES 加密技术，不仅在软件结构层面达到面向服务目的，同时保 证了系统通信的安全性。在软件详细设计阶段，利用了面向对象技术，定制服务契约，抽象服务接口，在保证系统横向伸缩性 良好的同时完成解耦。目前系统已经完成，并得到了很好的实际应用。

The article introduces the endoscopic traceable system and combines with the service-oriented structural characteristics and the system requirement to design a real service-oriented data center system. The system adopts WCF technology of .NET platform service, HTTP protocol and DES encryption technology. It not only can achieve the purpose in service-oriented on software structure layer, but also ensure the safety of communication system. In the software detailed design stage, it makes full use of objectoriented technology, customizes service contract and abstracts service interfaces to guarantee the system transverse expansion very well and completes the object directly decoupling. The current system has been completed, and obtains very good practical application.
