一、前言
计算机项目设计项目定制|源码教程基于django实现的原生微信小程序英语单词学习系统_哔哩哔哩_bilibili计算机项目设计项目定制|源码教程基于django实现的原生微信小程序英语单词学习系统共计2条视频，包括：E147 1196-基于django实现的原生微信小程序英语单词学习系统、学员项目售后答疑辅导必看教程等，UP主更多精彩视频，请关注UP账号。
https://www.bilibili.com/video/BV1Y44bewESA?t=293.2该项目含有源码、文档、PPT、配套开发软件、软件安装教程、项目发布教程、包运行成功以及课程答疑与微信售后交流群、送查重系统不限次数免费查重等福利！
本英语单词学习小程序系统的架构设计主要分为可以3层。系统架构如下图所示。
二、功能介绍
管理员在系统后台试题库模块可以查看到系统所有的试题库信息，试卷列表，考试记录和试卷管理等功能模块，在试卷库界面可以对系统所有的试卷名称，试题库名称，分值，答案，试题库类型进行修改，删除，新增的操作，在该界面可以通过试卷名称和试题库名称对试题进行单一的查询。
