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.
