The Research And Realization Of Grain Logistics Distribution System Based On SOA

Grain is the big matter of national livelihood, which is particularly prominent in recent years because of the instability in the international economic environment. Different time has different problems, and nowadays it becomes the main issue of information technology and modern logistics. China's Grain Bureau and the grain currency enterprises and institutions in this field are announced to start building information technology to achieve greater competitiveness by the government. In this procedure, we has made some achievements, but also had some problems, such as some of the internal operation sub-systems are too large and complex. As they are developed in different languages which cause the inconvenience in communicating, even can not be achieved in collaboration with each other. There is not enough investment in the Construction of logistics information technology, distribution path of the vehicle in areas, scheduling arrangements have not yet widely used. All these issues hampered to build good information technology in China's grain currency enterprises and institutions.Service-oriented architecture (SOA) is a new generation of thinking in the structure, loosely as well as good, platform-independent and other characteristics, and a very good solution to the system flexibility and interoperability, so SOA has a very wide range of applications. The current research, Web services are the way to realize SOA.In an deeply study of SOA and Web services technology, according to the problem we come across in grain currency enterprises and institutions, I build SOA-based grain logistics and distribution systems in this paper, using GIS technology and SOA to develop different function in the form of Web services , to solve information exchange system problems and achieve graphics and visualization.This article is mainly carried out in the following areas:(1) According to the status quo of China's grain currency enterprises and institutions in the field of information, pointed out and sum up the deficiencies.(2) Deeply study of the advantages of SOA and Web services technology, and related principles and norms of the agreement.(3) According to the analysis of the feasibility and demands, designed the system in detail regards on functions and business processes, and designed SOA-based grain logistics distribution system model and frame structure.(4) the use of service-oriented framework for the development of methods, through the level service model to realize the main functions of the system, and applied to the project, successfully solved the grain logistics information technology problems. It can offer valuable experience for the future study on this system.
