<li>预计学时：100 小时</li> </ul> <p>作为 CMU 数据库的入门课，这门课由数据库领域的大牛 Andy Pavlo 讲授（“这个世界上我只在乎两件事，一是我的老婆，二就是数据库”）。15-445 会自底向上地教你数据库系统的基本组成部分：存储、索引、查询，以及并发事务控制。 这门课的亮点在于 CMU db 专门为此课开发了一个教学用的关系型数据库 <a href=https://github.com/cmu-db/bustub>bustub</a>，并要求你对这个数据库的组成部分进行修改，实现上述部件的功能。此外 bustub 作为一个 C++ 编写的中小型项目涵盖了程序构建、代码规范、单元测试等众多要求，可以作为一个优秀的开源项目学习。</p> <h2 id=_2>课程资源</h2> <ul> <li>课程网站：<a href=https://15445.courses.cs.cmu.edu/fall2019/schedule.html>Fall2019</a>, <a href=https://15445.courses.cs.cmu.edu/fall2020/schedule.html>Fall2020</a></li> <li>课程视频：课程网站免费观看</li> <li>课程教材：Database System Concepts</li> <li>课程作业：4 个 Project</li> </ul> <p>在 Fall2019 中，第二个 Project 是做哈希索引，第四个 Project 是做日志与恢复</p> <p>在 Fall2020 中，第二个 Project 是做 B 树，第四个 Project 是做并发控制</p> <p>如果大家有精力的话可以都去尝试一下，或者在对书中内容理解不是很透彻的时候，尝试用代码写一个会加深你的理解。</p> <p>我在学习这门课中用到的所有资源和作业实现都汇总在 <a href=https://github.com/ysj1173886760/Learning/tree/master/db>ysj1173886760/Learning: db - GitHub</a> 中。</p> <p>由于 Andy 的要求，仓库中没有 Project 的实现，只有 Homework 的 Solution。特别的，对于 Homework1，我还写了一个 Shell 脚本来帮大家执行自动判分</p> <p>另外在课程结束后，我十分推荐阅读一篇论文 <a href=https://github.com/ysj1173886760/paper_notes/tree/master/db>Architecture Of a Database System</a>，对应的中文版我上传到了链接中的仓库。论文里综述了数据库系统的整体架构，让大家可以对数据库有一个更加全面的视野。</p> <h2 id=_3>后续课程</h2> <p><a href=https://15721.courses.cs.cmu.edu/spring2020/ >CMU15-721</a></p> <p>主要讲主存数据库有关的内容，每节课都有对应的 paper 要读，推荐给希望进阶数据库的小伙伴</p> <p>我目前也在跟进这门课，完成后会在这里提 PR 以提供进阶的指导</p> <hr> <div class=md-source-date>
