Design And Implementation Of Saft Logistics Information Management System Based On SOA

With the development of information technology, information technology is playing a more important role in improving the efficiency of enterprises. In the face of the wave of the information technology, logistics enterprises have also constructed the information management systems to enhance themselves in increasingly fierce industrial competition. However, in reality, owing to new small and medium-sized logistics enterprises not only have to face the pressure of surviving, but also are stuck with market expanding, it is difficult to make sure there are adequate human and material resources for constructing logistics information management system. While these enterprises also have an urgent need for logistics information system to improve efficiency of enterprise business operation and management, reduce costs and enhance the competitiveness of enterprises.As said above, this thesis is based on the mature platform of Microsoft’s.NET, we design and implement logistics information management system in lightweight SOA architecture(Service-Oriented Architecture) with utilizing the technology of ASP.NET, WCF(Windows Communication Foundation) and Entity Framework. With the help of features like loose coupling, good flexibility and strong expansibility, we can construct a logistics information management system which has low cost, high efficiency for small and medium-sized logistics enterprises to meet the practical needs of the enterprises, and this system will improve itself as the development of enterprises.First, we analyze the meaning and structure and advantages of SOA architecture, then expounds the core technology for implementing the SOA architecture--WCF framework, meanwhile, regard the research of key technology in the framework as preparation of designing and implementing the system.According to the different application scenarios of SOA systems in practice, we also analyze the potential security problems and security needs of SOA systems, study and present relevant security protocols and security technologies applied to improve system security.On the basis of the technical preparations, by analyzing the business needs of small and medium-sized enterprises, we design the system architecture and functions in detail and give a concrete implementation for each level of the system. The business should be service-oriented based on the architecture of SOA, what’s more, aims at different characteristics of business and distinguishes basic services, Windows services and mobile extension service, and expounds the implement of the triple services.Finally, on the foundation of implementing the basic architecture function and security analysis, we think of system characteristic and stand on the perspective of storage security, access control, data transmission, make use of mature technology, following the principle of optimal system consuming and security degree, put forward a security solution and implement in practice to improve the security factor of the system.
