Give a brief account of the History Manager.
What will be an ideal response?
History Manager is a modeling aid that helps keep track of the changes made to the source objects from which another object is constructed or derived. If the History Manager is turned on and an object is constructed from another object, the two objects will have a parent-child relationship. When you change the parent, the child will change accordingly.
