"监区业务系统设计与实现：面向对象的数据库应用软件开发"

Abstract: The "Prison Area Service System" is a database application software developed using object-oriented language Visual basic.Net for handling business operations at the grassroots level of prisons. This paper mainly introduces the steps of developing the application software: system analysis, system design, system implementation, and system testing. In the system analysis, various data required by the system are analyzed using data flow diagrams, data dictionaries, and system function structure diagrams. In the system design, the various functional modules of the system, the required database tables and table fields, and menu design are detailed. In the system implementation, the events and codes of the corresponding functional controls in the implementation form are given, as well as the methods of menu implementation. Finally, the main function source code of this system is provided. This system has functions such as data input, data storage, information query, and data analysis. It features a user-friendly human-computer dialogue interface, comprehensive functions, and convenient operation. Keywords: object-oriented, Visual basic.Net, prison, business system.
