2.系統(tǒng)的設(shè)計背景
???????隨著時代的變化，移動APP的種類和功能逐漸變得多種多樣，占用手機的內(nèi)存也隨之越來越大，拿手機游戲舉例，單獨一個王者榮耀，最初下載占用的內(nèi)存大概是10個G，后來隨著升級包的累加，漸漸游戲內(nèi)存占用能達到20個G甚至更多，為此人們對手機性能的要求也越來越高，因為如果存儲容量被占用太多的時候手機的運轉(zhuǎn)將變得越來越慢，但與此對應(yīng)的是越高性能的手機價格就越高，且高頻的卸載安裝也會更加縮短手機的使用壽命，并非大眾都能負擔(dān)，因此幾乎不占內(nèi)存，隨開隨用的小程序APP就變得炙手可熱起來。
???????盡管隨著時代的遷移，計算機技術(shù)的發(fā)展越來越快，但其核心仍舊不變，大到阿里，知乎等知名大廠的項目，小到個人開發(fā)的小游戲，簽到系統(tǒng)，讀書筆記等，其目的都是為了給人們提供更好的生產(chǎn)生活服務(wù)，本文基于校園簽到場景，為解決課堂簽到時間長，簽到準(zhǔn)確率不高等問題，設(shè)計了一個基于微信小程序開發(fā)的學(xué)生課堂掃碼考勤簽到系統(tǒng)，使用工具為微信開發(fā)工作者，后端開發(fā)語言為java，數(shù)據(jù)庫使用了常用的mysql，采用的后端框架為Sspringboot，是前后端分離開發(fā)，設(shè)計模式上采用了mvc的設(shè)計模式，令數(shù)據(jù)層，業(yè)務(wù)層，視圖層可以解耦合，有利于后續(xù)的更新維護工作。
