枣品质决策系统——数据导入设计.doc

Abstract: The decision-making system for jujube quality is designed to address the issues faced by fruit farmers due to the lack of professional knowledge in assessing the quality and correct value of their jujube fruits. This system utilizes the current networked and fast-paced information environment to provide comprehensive information evaluation services, such as network-based assessment of fruit quality and relevant recommendations. The server system of this design can update and rebuild decision trees based on real-time data, and users can also query functions based on collected data. This paper mainly focuses on the functional logic of the system, analyzing in depth the implementation principles and solution selection of sub-functions. It provides a detailed introduction to the methods of data import and export in web application systems, using open-source technologies such as Java and JXL (Java Excel Api). JavaWeb was selected as the development language for this project, incorporating object-oriented development thinking and the design principles of MVC (Model-View-Controller) pattern. In terms of interface design, data encapsulation and information hiding have been implemented. Keywords: JavaWeb, batch data, import/export.
