Research On Logistics Management System Of Tropical Agricultural Products Based On SOA

With the rapid development of tropical agriculture, tropical agricultural products logistics, as a core part of achieving agricultural value, has become the focus of attention. Logistics information is the central nervous in tropical agricultural products logistics, which generates by the occurrence of the logistics activities in the tropical agricultural products; to grasp and manage the logistics information is helpful for companies to monitor the logistics activities effectively. The existing logistics information systems are general technology-oriented, universal existence many problems, such as not strong practicality, difficult information sharing, low flexibility of business, poor agility, etc., unable to meet the requirements of short logistics cycle and fast circulation speed of tropical agricultural.Based on the deep analysis of tropical agricultural products logistics supply chain, it establishes the tropical agricultural products supply chain model around the processing enterprises, which can shorten the distance of production and marketing, and optimize the supply structure of tropical agricultural products. Around the core enterprises, it analyzes the key business processes of tropical agricultural products logistics. Aiming at the flexible characteristics of the business process and scalability requirements of system, it builds logistics information system for tropical agricultural products processing enterprises based on the idea of SOA. SOA has a good loose coupling, and platform-independent features, which is well positioned to meet the needs of the system.To design and implement the Logistics Information System of Tropical Agricultural Products in the guiding ideology of service-oriented design idea. Firstly, encapsulating the function of the system into service, and dividing services into atomic services, composite services and composite services, as a collection of candidate services composed of business processes, to improve response speed of business requirements changing; secondly, in the architecture design of the overall system , using the integration approach of hierarchical structure and service-oriented, the system is divided into presentation layer, service layer, business logic layer and data access layers, and carrying out a detailed description for the design of layers; again, after determining the principles of database design, it establishes database design model of the core business; finally, based on the above analysis and design methods, in the. NET platform, it builds logistics information system of tropical agricultural products, focusing on Web service call and implementation, and the realization of business processes, then, showing the combination process of business processes through example.It puts forward building the supply chain model around the processing enterprises and design and implement the system based on SOA, general meet the needs of tropical agricultural products logistics, the design is flexible, easy to use, providing a solution for the expansion and reconstruction of the system. It achieves good results in practical application,provides a good reference and the reference value for the further development of logistics information system in agricultural products.
