Provide a sketch of the things you could use for data right now. How are they organised? Are they simple single structures or are they part of something bigger? Do they store things or are they stored by things?

My bookcase infront of me has over 300 books in it. It isnt organsied in any noticable due to size but are ordered according to their genre or topic. The bookcase is a single structure but the books themselves are apart of something bigger. Each book stores its own information and then the bookcase stores all of that information inside of it.
