I was hoping to build a simple relational database as a side project, focussing mainly on learning how the internals and the algorithms used work, as I never plan to make this a published product of any sort.
So far I have the CMU Advanced DB course (https://15721.courses.cs.cmu.edu/spring2024/) and the Database Internals book.
While I'm learning a lot about how databases work, I have no clue how to start writing my own, so I was wondering if there were any resources for building a relational database, I've only found some for KV Stores. Hopefully something less intimidating to get started than having to read SQLite code.
