2 系统可行性分析
2.1 技术可行性分析
点菜信息管理系统将Sqlite作为数据库，Sqlite作为开源的关系型数据库，并且具有成本低、体积小、速度快等特点。整个系统是基于Django框架搭建的，Django框架本身就已经拥有了很多基础性的功能，不需要再去重复的完成大量的编码工作，提高了程序的规范性和代码的重用性。采用Bootstrap4 + jQuery作为前端的技术支持，后台使用Python面向对象语言。由此可见，实现点菜信息管理系统在技术上是完全可行的，并且可以完成点菜信息管理系统所需要的基本功能。
2.2 经济可行性分析
从目前的社会现状来看传统的点菜模式不仅浪费时间，效率低下，而且特别耗费成本与人力。于此不同，使用点菜信息管理系统能大大降低人力的成本这样就节省了相对应的成本开销，避免人员的冗余，并且开发系统使用的工具和技术都是开源的，投入该系统的成本并不高。所以对于餐馆来说开发一个点菜信息管理系统在当前的资金投入和使用该系统降低的成本上是可以接受的，由此来看此系统从经济上来看是可行的。
2.3 操作可行性分析
该系统使用的技术都是目前大众普遍使用的，并且操作简单，业务逻辑流程条例清晰，使用方便，并且用户使用起来上手快，容易理解，不需要理解太深的东西。由此来看，该系统从操作上来看是可行的。
3系统分析
3.1 系统功能分析
该系统为点菜管理信息系统。网上点菜系统是一种可以自主选择、个性化、便捷化、特色化的点餐模式，它的大力推广使用为餐厅节约了成本，同时也解决了消费者在传统点菜时存在的不少麻烦。通过对系统的需求进行分析得出，该系统的功能模块分为三种，分别是管理员模块、用户模块、后厨模块，并且各个用户模块下对应着各自的功能实现。
3.1.1 管理员模块
（1）管理员登录：对于已经存在管理员可进行登录。
（2）订单信息查询：管理员可以查询系统内所有存在订单。
（3）职工信息管理：管理员可以登录该系统对已经注册的职工个人信息进行增加、删除、改动、查找等操作。
（4）餐桌信息管理：管理员可以对该系统对已经存在的餐桌信息进行增加、删除、改动、查找等操作。本文转载自http://www.biyezuopin.vip/onews.asp?id=15595
（5）菜品信息管理：管理员可以对该系统对已经存在的菜品信息进行增加、删除、改动、查找等操作。
