Dependency Diagram 3nf. Create a database whose tables are at least in 3nf showing the dependency diagrams for each table. In this case c is transitively dependent on a via b.
Create a database whose tables are at least in 3nf showing the dependency diagrams for each table. Primary key for our score table is a composite key which means it s made up of two attributes or columns student id subject id. Main steps of normalization.
Assume the tables are already in inf.
A relation is said to be in third normal form when it is already in first normal and second normal forms and every non prime attribute is non transitively dependent on superkey of relation or in simple language there is no transitive functional dependency.
