Answer to Question 1

Business classes are those that have a counterpart in the real world: tree, student, contract, office, poet, shirt, patient, etc. The discovery of business classes and their relationships is the main task of analysis. Utility classes are those that lack a direct counterpart in the real world and are used to create objects that manage the responsibilities of the information system: to interact with the outside world, to make communication among business objects possible, and to save information when required. Command buttons, menus, and dropdown lists are a few such classes. Discovery and definition of utility classes and their relationships is the task of design.

Answer to Question 2

B
