Answer 1

If a dimension has a FK that relates it to another dimension, that's called a snow flake. Here is what folks on the Kimball forum have to say about it http://forum.kimballgroup.com/t460-start-schema-vs-snow-flake-schema

Snow flakes are conceptually correct, but they do add complexity so you will need to put thought into when you use them.
