2.系统的设计背景

       随着时代的变化，移动APP的种类和功能逐渐变得多种多样，占用手机的内存也随之越来越大，拿手机游戏举例，单独一个王者荣耀，最初下载占用的内存大概是10个G，后来随着升级包的累加，渐渐游戏内存占用能达到20个G甚至更多，为此人们对手机性能的要求也越来越高，因为如果存储容量被占用太多的时候手机的运转将变得越来越慢，但与此对应的是越高性能的手机价格就越高，且高频的卸载安装也会更加缩短手机的使用寿命，并非大众都能负担，因此几乎不占内存，随开随用的小程序APP就变得炙手可热起来。

       尽管随着时代的迁移，计算机技术的发展越来越快，但其核心仍旧不变，大到阿里，知乎等知名大厂的项目，小到个人开发的小游戏，签到系统，读书笔记等，其目的都是为了给人们提供更好的生产生活服务，本文基于校园签到场景，为解决课堂签到时间长，签到准确率不高等问题，设计了一个基于微信小程序开发的学生课堂扫码考勤签到系统，使用工具为微信开发工作者，后端开发语言为java，数据库使用了常用的mysql，采用的后端框架为Sspringboot，是前后端分离开发，设计模式上采用了mvc的设计模式，令数据层，业务层，视图层可以解耦合，有利于后续的更新维护工作。
