Extract of sample "The Entity Life History for Booking"

Question First normal form (1NF) means that Extra_Form entity must have a primary key. Duplicate field is removed. Second normal form (2NF) means that Bar_Lounge_Restaurant is put to the separate table and relationship between it and Extra_Form is created. Third normal form (3NF).

A Booking's life begins with a "Booking creation", and ends with a "Booking end". In between, its "Booking life" consists of some "Booking events".
