Object-Oriented Approach Catalog objects – Found by keywords – In a Library or Database Objects – Exhibit certain behaviors – Attributes and operations are encapsulated or pulled together – Operations describes how attributes are processed – Behave in certain ways in response to messages

Object-Oriented Approach Classes Set of objects that share common structure and behavior Inheritance Objects receive attributes and operations from other objects Add more attributes and operations of their own Polymorphism Ability of object to respond to and Implement each object
