Which of the following statements are true related to constraints? Select one or more: a. When an entity instance may be a member of multiple subtypes or it does not have to be a member of subtype the specialization is overlapping and total. b. When an entity belongs to only one sub type in the hierarchy the relationship is total and disjoint. c. A bowler and batsman(assume wicket keeper is also a batsman) which are sub types of a cricketer type total and disjoint d. If a subtype participates in a relationship that is the same as the other subtypes that relationship could added to the super type

Step 1
Specialization constraints define how entities in a superclass/subclass (or supertype/subtype) relationship are organized. There are two main types of constraints: disjoint vs. overlapping and total vs. partial. - Disjoint vs. Overlapping: A disjoint constraint Show more…

Which statement about abstract classes and interfaces is false? (A) An interface cannot implement any non-default instance methods, whereas an abstract class can. (B) A class can implement many interfaces but can have only one superclass. (C) An unlimited number of unrelated classes can implement the same interface.
