前言
随着科学技术的飞速发展，社会的方方面面、各行各业都在努力与现代的先进技术接轨，通过科技手段来提高自身的优势，新能源汽车在线租赁当然也不能排除在外。新能源汽车在线租赁是以实际运用为开发背景，运用软件工程开发方法，采用SSM技术构建的一个管理系统。整个开发过程首先对软件系统进行需求分析，得出系统的主要功能。接着对系统进行总体设计和详细设计。总体设计主要包括系统总体结构设计、系统数据结构设计、系统功能设计和系统安全设计等；详细设计主要包括模块实现的关键代码，系统数据库访问和主要功能模块的具体实现等。最后对系统进行功能测试，并对测试结果进行分析总结，及时改进系统中存在的不足，为以后的系统维护提供了方便，也为今后开发类似系统提供了借鉴和帮助。
本新能源汽车在线租赁采用的数据库是Mysql，使用SSM框架开发。在设计过程中，充分保证了系统代码的良好可读性、实用性、易扩展性、通用性、便于后期维护、操作方便以及页面简洁等特点。
数据库设计原则
学习编程，我们都知道数据库设计是基于需要设计的系统功能，我们需要建立一个数据库关系模型，用于存储数据信息，这样当我们在程序中时，就没有必要为程序页面添加数据，从而提高系统的效率。数据库存储了很多信息，可以说是信息管理系统的核心和基础，数据库还为系统提供了添加、删除、修改和检查等操作模块，使系统能够快速找到自己想要的信息，而不是在程序代码中找到。数据库中信息表的每个部分根据一定的关系精确地组合，排列和组合成数据表。
通过新能源汽车在线租赁的功能进行规划分成几个实体信息，实体信息将通过ER图进行说明，本系统的主要实体图如下：
