Elaborate on "classes as building blocks of structural modeling and objects as units of information systems."
What will be an ideal response?
A structural model is distinguished from another structural model by the nature of its building blocks (or units) and how the units are connected. The structural model of information systems is composed of classes and their interrelationships. At runtime, when the information system is actually created, classes are "instantiated" into objects that function as the units of the information system. In other words, classes act both as units of modeling and as templates for units of the information system.
