Why Generalization Is Very Strong


  • 5 Jan, 2012

    Even though Generalization satisfies Structural, Interface, Behaviour properties. It is mathematically very strong, as it is Antisymmetric and Transitive.Antisymmetric: employee is a person, but not all persons are employees. Mathematically all As? are B, but all Bs? not A.Transitive: A=>B, B=>c then A=>c.A. Salesman.B. Employee.C. Person.Note: All the other relationships satisfy all the properties like Structural properties, Interface properties, Behaviour properties.
