Development Of Agricultural Science And Technology Achievements Trading And Service Portal Website And Research On Information Sharing Technology

In the transformation process,agricultural science and technology achievements are affected by many factors.Many achievements can not be transformed effectively.In order to promote the transformation of agricultural science and technology achievements,it's an urgent need to construct an information platform for the achievement trading service that facilitates the docking of supply and demand and focuses on tracking service and information sharing.The thesis focuses on the key research and development plan of Jiangsu Province in 2016,"Key Technology Research and Integrated Application Demonstration of Agricultural Science and Technology Achievements Trading and Service Cloud Platform in Jiangsu Province",and aims to break the closed and asymmetrical information and resources and promote the application of agricultural science and technology achievements.The main research content includes: based on the deep research on the key technology of the cloud platform,the overall architecture of the system is determined,the database of the system is designed and platform data center is established;the cloud portal is developed,as well as public information service,integrated management service,single sign-on service,site search engine,messaging service and other subsystems,and the server of the cloud portal is deployed;data collection and sharing interface based on web crawler is designed,achieving the sharing of achievements data;after completing the deployment of the cloud platform,detailed tests and system improvements are carried out in terms of functions,security and concurrent performance.The organizational structure of each chapter is as follows:The first chapter is the introduction,which mainly introduces the origin and significance of this topic,the research status at home and abroad,the main research contents and the organizational structure of the thesis.The second chapter is the introduction of the overall scheme of the system,introduces the design goal and overall structure of the system,and analyzes the related technologies used in the system.The third chapter is system database design,analyzes the data characteristics and the relational structure in the system,and designs the data table format.The fourth chapter is cloud platform deployment and portal server software design,analyzes the technology used in the realization of the server,and introduces the system architecture and the realization process of each subsystem.The fifth chapter is the design of the portal client software,introduces the operation logic and implementation process of the client front-end page and the background management page.The sixth chapter is about data sharing technology,introduces the principle and implementation of the crawler technology,and details the whole realization process from standard set,achievement collection to sharing interface design.And the problems encountered are analyzed.The seventh chapter is system testing and running,and introduces the test and operation of the system.The trading and service platform for agricultural science and technology achievements formally launched and went online in December 2017 by the Science and Technology Department of Jiangsu Province.The system is stable and has played a catalytic role in the transformation of achievements in Jiangsu Province.
