(Solved) : 1 5 Points Consider Following Relational Mapping Specialization 1 Superclass Entity N Subc Q34743756 . . . .

1. a) (5 points) Consider the following relational mapping of aspecialization with 1 superclass entity and n subclassentities:

i) A single relational table that has all attributes of thesuperclass entity and the subclass entities, i.e. 1 tabletotal.

ii) One relation for each subclass entity that includes theattributes of that subclass entity as well as the attributes of thesuperclass entity, i.e. n tables total.

iii) One relation for each of the entities, i.e. the subclassentities as well as the superclass entity, i.e. n+1 tabletotal.

In the following table, state if the solution is consistent orinconsistent with the constraint. If additions are necessary, statewhat they are.
