The Design And Implementation Of Pilots Management Information System

In recent years, with the rapid development of China's aviation industry, more and more problems of the management of pilots have appeared. There are so many pilots that their structure is very complicated, the information of troops and pilots can make lots of data so that it is very difficult to be managed and its security is hard to guarantee, besides, the management of information and logical relationship can't be effectively inherited bacause of the adjustment of many pilots. Considering the problems above and the actual demands of Naval Equipment Research Institute, the thesis designs and implements the information of pilots management system. The main work of the thesis is as follows:(1) Analyze the background and meaning of the information of pilots management system. According to the technical proposal of the existing management information system, study techniques such as Dev Express,.NET and database.Analyze the working mode of pilots management and summarize the demands by using the activity diagram and flow charts. Analyze and modularize functional demands, besides, summarize the key problems and non-functional demands of the system.(2) The thesis designs a overall plan of the system according to the requirements.Based on the traditional MVC design pattern, the model layer is divided into business logic layer and data persistence layer so that the system is easier to be maintained and expanded. Architecture diagrams are used to achieve the detailed design of the system.Database entities, tables and the table relationship diagrams are used to achieve the detailed design of the database and data dictionary. Based on the comparation of the MD5 and SHA1 algorithm and the analysis of the system login process and log,achieve the detailed design of security.(3) According to the design of the system. The thesis implements the information of pilots management system on.NET platform, including integrated information managementmodule, statistics managementmodule, bulletin information managementmodule, data managementmodule, dictionary managementmodule and system managementmodule and other functional modules. First, the development environment of the system and system configuration such as Dev Express, Oracle areintroduced. Then, the system framework is described by sequence diagram, class diagram, code and interface implementation diagram. At last, describe the implementation of each module in the system and the realization of security by the form of flow chart and key code.The whole project has already been finished and used, the function and performance of the system have both reached the design demand during the process of using it, and it works very well, and is nice received by users.
