Your reply will be a great help to us! ^_^

Hi
PK is short for Primary Key and is data attributes that uniquely identify an entity.
FK is short for Foreign Key and is a reference to the primary key of another entity.
PF is short for Primary Foreign Key, and when a foreign key of an entity also is a part of the primary key the attribute will be indicated with 'PF' behind its name.
PLEASE :) try to Google before posting so you at least know what you are asking about.. Otherwise the result can be answers that is wrong because people do not really understand what you mean. And how can they if you do not know that yourself:?
Here you have a quick Introduction to database design:
