Design And Realization Of Web Issuing Application System Of Vegetable Production And Management Information Of Jiangsu Province Based On WebGIS

With constant development of the vegetables production in our country, it is more and more difficult to manage vegetables production. Developing management information system of vegetables production can help to vegetables production management. Using a set of modern information technologies, such as WebGIS, ASP, database, etc., on the basis of an intensive study of key technologies and methods for system developing, a web issuing management information system of vegetables production of Jiangsu Province was developed, which was a successful combination of modern information techniques with vegetables production management.The dissertation is composed of 7 chapters. In the preface, the purpose and significance of the study were clarified, the recent development of related research at home and abroad was synthesized, and the basic idea, research methods and structure of the dissertation were expounded. Chapters from II to VI were focused on factors analysis related to this application system. In chapter II, some developing technologies of application program on web at present and their characteristics were analyzed, and a developing technology was applied to develop dynamic web page at last. In chapter III, basic fundamental principle of WebGIS, GIS and their applications were simply analyzed, then some popular odd GIS application software were made pertain and contrast, and an application software was Chosen as released-platform of WebGIS. In chapter IV, functions of system's components were analyzed, and a systematic design plan of function was given. The design plans of the customer end and server end were discussed. In chapter V, the design plans of spacing database and property database were given, the security of web database was discussed, with an emphasis on process of access and query, and some codes of connect to database, access to database, close connection, etc. were given. In chapter VI, The performance of every function's realization was elaborated, and some key-codes were given. In addition, the implementation method of security measures was given. In the last chapter, summary of the study was made, and suggestions on further improvement of this system were put forward.
