Is there any book/textbook course out there that goes through how to write a database or dbms from scratch up to something useful, think something like nand to tetris style? I have been looking but there is not much on this topic out there I feel like.

There is a book that is exactly this, "Database Design and Implementation" by Edward Sciore.

You write a database in Java while having the principles explained along the way.
