Infer PKs and FKs

There can be several reasons why you don't originally have Primary Keys and/or Foreign Keys in your model: - you have a data model loaded from a source that did not provide them; - you reverse-engineered from a Big Data Analytics platform that don't support these constraints; - you decided not to enforce PK and/or FK constraints for performance reasons This feature identifies candidate PKs and PKs to be added to your model. The algorithm works on the metadata of the entities and attributes without looking at the actual data.
