I went through Sciore's book [0] while learning about relational database internals. As part of his book, the author also developed a minimal database system named SimpleDB [1] in Java. I can safely say that its source code is very easy to understand. Though the book is not free, SimpleDB is.

Thanks for sharing this! I had been looking for something like this for a long time.
Sadly, the book has a ridiculous price.
Gladly, the course notes from the author is freely available. The book closely follows it:
