Difference between Folder, Document, NodeRef, and StoreRef?

[dan]

Hi all.

I've been trying to understand the difference between these 4 terminologies in Alfresco Java API? 

Is a NodeRef part of a Folder and Document as unique idendifier?

How's StoreRef related to NodeRef?

Any examples are appreciated, or links to explanations.

Thank you all.#
