Based On Com Technology Irrigation Management Information System Design And Implementation

The development of Management Information System for Irrigation and the realization of the computerization of the irrigation management are important to promote our country's irrigation district to be more modernized and more standardized. With the rapid development of the information technology, the way of processing information is increasingly depending on the computer instead of processing it by hand. Coincide with this trend, irrigation management has put forward higher request to the transmission speed and dependability of the information. Establishing the highly-efficient and highly-reliable management information system for irrigation based on the computer has become the essential demand of social development.The development of software technology mechanism, especially the advent of object-oriented programming idea and component object model (COM) technology, brings new methods of developing software for all application systems including GIS. 'Management Information System for irrigation based on COM technology' is not only beneficial for the development of management information system for irrigation, but also meet the requirement of searching and analyzing irrigation information. This thesis studies the design scheme, accomplishment method and key technology in detail. The main content can be summarized as follows:1. Analyze the special requirement and the features of the irrigation information.2. Design the technology schema and the framework of "Management Information System for irrigation "and the plan about how to divide the functional model, how to organize the data, how to construct database.3. Research the implementation method for main function in system, the flow of constructing database and the scheme to solve problems for key technology.4. Take the data of Yanhu district of Shanxi province as an example, develop the 'Management Information System for irrigation in Yanhu district' based on 'Management Information System for irrigation'.After studying all of these, I put forward the scheme for design and integration of management information system for irrigation based on COM, designed the database for the system. The major problems that are solved are as follows: data standardization, data editing, data management, professional query and analysis of irrigation information. At present, the principal parts of 'Management Information System for irrigation in Yanhu district' has been completed and used in Yanhu district.
