Design And Implementation Of TMS Based On WCF Framework

At present, with the rapid development of information technology, logistics industry has begun comprehensive application of Internet technologies, created a Web site, freight companies also took a blind leap into the area of electronic commerce. This article is aimed at the scope of our logistics industry customers business, overall job level lower, logistics resources utilized by a number of factors, the system used the .NET Framework to design and implement a based on the .NET platform B/S schema of TMS. On the concept of WCF are certain research and explains, presented under the .NET platform based on the WCF framework of four-tier development of TMS thought and method.The main content of this article contains the following aspects:1,System architecture aspect: TMS in the foundation of service-oriented infr astructure, used logical four tier frame pattern, divided system into the presenta tion layer, WCF service layer, business logic layer, and data access layer.2,System business aspect: the system picked up the important and similar b usiness function as the WCF, the system service is consist of Login.svc,Order.sv c,Shipment.svc,AssignFunction.svc,BaseInfo.svc,Financials.svc,Report.svc and so o n.3,System design aspect:The TMS design according to the physical design, the logical design, the internal connection design, the database design ,the safe design's order carries on the introduction.4,System implementation aspect: the implementation's introduction of TMS accord to the presentation layer, WCF service layer, business logic layer,data-access layer, Each layer are introduced from the global to the specific, theprese ntation layer using asp.net for data display, The WCF service layer has adopted the reputation type programming and the disposition combines in the togetherwa y, enable the service to obtain the biggest flexibility, Business logic need simult aneously to operate multiple of data table for achieve a particular business logic, each Table may be a separate operation, these operations combined together to complete a business logic, Data access layer is the bridge between business logi c and database, mainly in the data request into a SQL statement. Finally, thesys tem's exception handling and performance make the specific analysis and imple mentation.
