基于Android的汽车油耗信息管理系统的UML模型

UML Model Design for Management of Information of Car Oil Consumption Based on Android OS

摘要: UML是一种用于构造可视化、文档化的图形建模语言。在需求分析的基础上，对基于Android平台的汽车油耗信息管理应用系统，使用UML建模工具，分别建立了添加加油信息UML模型、添加加油站UML模型、加油信息管理UML模型、油耗统计UML模型等，完成对应用软件的分析与设计，采用Java语言完成对应用软件的开发。对油耗统计提出了基于剩余油量的计算方法，比传统的加油灯计算油耗方法更准确有效。实践表明，UML分析可以有效构建系统模型并提高应用软件的开发效率。

Abstract: UML is a graphical modeling language for visualized construct and documentation representation. After demand of the function is analyzed, UML models of oil information appending, gas stations appending, oil information management and car oil consumption statistics are founded respectively based on UML tool in the information management system of car oil consumption on Mobile with Android OS. Then analysis and design of the application software are implemented. The application software is developed by using Java. The calculation method of car oil consumption is proposed based on the amount of oil left. It is more accurate and effective than traditional method which is based on oil lamp. The actual system shows that UML could be used to build system models effectively and also could improve the efficiency of application software development.
