An Introduction to Object-Oriented Design
Design Objects
- The objects that represented actual data within the business domain in which the user was interested in storing were called Entity Objects.
- Objects which represent a means through which the user will interface with the system are called Interface Objects.
- Objects that hold application or business rule logic are called Control Objects.
- A system’s functionality is distributed across all three types of objects.
- This practice makes the maintenance, enhancement, and abstraction of objects simpler and easier to manage.
