What is non conformed dimension?

A non-conformed dimension is where you add an attribute to an analysis which does not logically relate to all the facts. Take this example, here we have an analysis with 2 "facts" and 1 "conformed dimension" i.e. the "Store" dimension attribute relates to both "# POIs" and "# Orders".

Are fact tables normalized or denormalized?

The fact table is in normalized structure as the redundant information is maintained in the dimension tables. Generally it is the schema that is denormalized than just the fact table.
