1、项目介绍及开发技术

1.1 项目介绍

传统办法管理信息首先需要花费的时间比较多，其次数据出错率比较高，而且对错误的数据进行更改也比较困难，最后，检索数据费事费力。因此，在计算机上安装餐厅点餐管理系统软件来发挥其高效地信息处理的作用，可以规范信息管理流程，让管理工作可以系统化和程序化，同时，餐厅点餐管理系统的有效运用可以帮助管理人员准确快速地处理信息。

餐厅点餐管理系统在对开发工具的选择上也很慎重，为了便于开发实现，选择的开发工具为Idea，选择的数据库工具为MySQL。以此搭建开发环境实现餐厅点餐管理系统的功能。其中管理员管理用户，新闻公告。

餐厅点餐管理系统是一款运用软件开发技术设计实现的应用系统，在信息处理上可以达到快速的目的，不管是针对数据添加，数据维护和统计，以及数据查询等处理要求，餐厅点餐管理系统都可以轻松应对。

1.2 开发技术

Java开发语言、SpringBoot、MyBatisPlus、MySQL数据库、Maven、IDEA开发工具、JDK1.8+、Vue、HTML、CSS、JS。

3、功能截图

3.1 前台功能

登录后，用户能够查看菜品信息。页面如图所示:系统软件主页是餐厅点餐管理系统取得成功启动时的主页。那样能够看见系统软件前台接待主页的规划和实现。

商品信息

?购物车信息

3.2 后台功能

用户信息管理：用户信息的查询管理，可以删除用户信息、修改用户信息、新增用户信息，

还进行了对用户名称的模糊查询的条件。

?商品信息管理：查看已发布的商品信息数据，修改商品信息，商品信息作废，即可删除，还进行了对商品信息名称的模糊查询商品信息信息的类型查询等等一些条件。

广告信息管理：?根据广告信息进行条件查询，还可以对广告信息进行新增、修改、查询操作等等。

菜谱咨询管理：根据菜品资讯进行新增、修改、查询操作等等。
