@ What would be the general rule for mapping A and B entity into relation? 5 Marks

A. what would be the constraint on foreign key, if;

  1. Minimum Cardinality = 0
  2. Minimum Cardinality = 1

Q: 06 I’ve forgot

 Best of luck to all students

 

One question was to find entities from the given scenario.

One was to identify the relation in a particular form and to give reason to justify the answer.

In one question it was ask to convert the relation in next normal form.

One question was from relational model.

For MCQZ do prepare KEYs related concepts, Functional dependencies, types of relationships & constraints

>>constraints enforces entity integrity

>>relationship exists between Grade and Student entities

 

Best of Luck!
