Statement A:An Entity is an object of Entity Type and set of all entities is called as entity set.Statement B:Set of the same type of relationships is known as 'relationship set

Statement A: Yes, in the context of database management, an entity is indeed an object of a specific entity type. An entity can represent a real-world object or concept, such as a student or a course in a university database. The entity set, then, refers to a collection of similar types of entities. For example, in a university database, the entity set of 'Student' would include all student entities.

Statement B: Similarly, a relationship set refers to a set of similar types of relationships. In a database, a relationship is a situation that exists between two relational database tables when one table has a foreign key that references the primary key of the other table. So, a 'relationship set' would include all similar types of relationships. For example, in a university database, the relationship set 'Enrollment' might include all relationships between the 'Student' and 'Course' entities.
