Normalization works through a series of stages called normal forms. The first three stages are described as first normal form (1NF), second normal form (2NF) and third normal form (3NF). From a structural point of view, 2NF is better than 1NF and 3NF is better than 2NF.

The result is the creation of a new relation called PropertyForRent (3NF) and Owner (3NF). In summary, the process of normalizing the PropertyRentalOwner (1NF) relation resulted in the creation of the Rental (3NF), PropertyForRent (3NF), and Owner (3NF) relations, which together with the Client relation is the same four relations created from ...

If the 3NF column contains groups of fields related to students, classes, and teachers, sensible entity names might be Student, Class, and Teacher. Because each entity will eventually be implemented as a relational table, take a moment at this point to double-check that each group in the 3NF form that corresponds to an entity name (that is ...
