I think a high-level B-tree explanation would be interesting — but perhaps you could warn that this needs some CS fundamentals (trees)?
Your approach to the library metaphor is interesting — I actually thought of it one level up, i.e. "a table is like a library" because I was thinking about a book as a row in a table. For example, a book has many properties (like genre, publish date, content, title, authors…) that we can relate to columns and relationships. Also, I'd be cautious not to cause confusion because "page" also have a specific meaning in the realm of databases (grouping of rows stored on disk). :-)
Anyway, excited to read this next article!
This is why I’ve held off tackling indexes so far. I’d like to pitch it to beginners but feel like I’m going to get too far into CS topics I wasn’t intending to explain.
Back to the draft :)
