Relational Database Schema
Relational database schema on every table was already shaped 3NF.
Because:
- 1NF requirement has been fulfilled, namely: there are no multivalued atribute or nested relations.
- Terms of 2NF was fulfilled, namely: no nonkey every attribute to be functionally dependent on a part of the primary key.
- 3NF terms have been met, namely: there is no transitive dependency. A fuctional dependency X -> Y in a relation schema R is a transitive dependency if there is a set of attributes Z that is neither a candidate key nor a subset of any key of R, and both X -> Z and Z -> Y hold.
