基于数据库的选课系统设计与实现 汇报型风格 幻灯片 1: 封面页 标题: 基于数据库的选课系统设计与实现 副标题: 项目架构、核心流程与成果汇报 汇报人: (您的姓名) 日期: (汇报日期) 幻灯片 2: 项目概述 标题: 项目概述:挑战与目标 核心目标: 设计并实现一个支持复杂业务规则、安全可靠的在线课程选择系统。 关键业务约束: 1. 先修课程: 学生必须先修完指定课程,才能选择更高级的课程。 2. 学分上限: 单个学期内,学生所选课程的总学分不得超过21分。 3. 时间冲突: 学生所选的多门课程之间,上课时间不允许有任何重叠。 技术栈: 后端 Spring Boot + MyBatis + Spring Security + JWT;前端 Vue.js + Element Plus;数据库 MySQL。 幻灯片 3: 系统架构设计 标题: 系统架构:清晰的三层分离模式 内容: 前端(Vue.js)、后端(Spring Boot)、数据库(MySQL)三层分离架构,数据流清晰,职责明确。 视觉: 三层架构图 幻灯片 4: 后端架构详解 标题: 后端架构:高内聚、低耦合的分层设计 内容: MVC分层结构,Controller负责请求接收,Service负责业务逻辑,Mapper负责数据访问。 视觉: 自上而下垂直堆叠的分层图 幻灯片 5: 核心流程 (1) - JWT安全认证流程 标题: 核心流程 (1) - JWT安全认证流程 内容: 登录生成JWT;前端携带JWT访问接口;后端验证JWT有效性。 视觉: 用户、前端、后端交互的时序图。 幻灯片 6: 数据库设计 - 总体思想与E-R图 标题: 数据库设计:支撑复杂业务的核心 内容: 采用实体-关系分离设计,核心实体 students, courses, enrollments, prerequisites, student_transcripts。 视觉: E-R图。 幻灯片 7-11: 数据表详解 分别介绍 students、courses、enrollments、prerequisites、student_transcripts 表的字段及作用。 幻灯片 12: 核心流程 (2) - 选课校验流程 标题: 核心流程 (2) - 选课校验流程 内容: 按“先修课程→学分上限→时间冲突→插入选课记录→更新课程人数”流程执行。 视觉: 校验流程图。 幻灯片 13: 系统功能演示 标题: 系统功能演示 内容: 登录页面、课程列表、选课失败与成功提示、“我的课程”截图展示。 视觉: 截图及箭头标注。 幻灯片 14: 总结与展望 标题: 总结与展望 内容: 系统完成度高、安全稳定;未来扩展教师/管理员角色、性能优化、用户体验提升。 幻灯片 15: end 标题: 谢谢观看,敬请提问! 风格说明: 汇报型风格,简洁专业,标题明确,色调建议使用蓝白科技风,强调逻辑与结构清晰。

本汇报展示选课系统设计与实现,涵盖项目目标(支持先修、学分上限、时间冲突规则)、三层架构(Vue.js+Spring Boot+MySQL)、JWT认证与选课校验流程、数据库E-R图及表设计、功能演示及未来展望。系统安全稳定、高度完成。(128字)

Slide 4 - Backend: High-Cohesion, Low-Coupling Layers

  • Controller: Receives HTTP requests, routes to Service.
  • Service: Handles core business logic, calls Mapper.
  • Mapper: Manages data access and persistence.
  • Vertical layers ensure high cohesion, low coupling.
