Domain Analysis Exercise

Software reuse can be improved by identifying objects and operations for a class of similar systems, i.e., for a certain domain. In the context of software engineering, domains are application areas. Common objects and operations are likely to occur in multiple applications within a domain and thus are candidates for reusable components.


Domain analysis produces the domain model that presents a general interpretation of the problem domain. The domain model defines the concepts of the domain and the terminology used, as the software development organization understands them. Thus, the domain model could model, for example, such domains as banking, car rental, telecommunication networks, or others without any software system as a target. Such a model provides a good foundation for the analysis class diagrams of future applications.

Learning outcomes

The material and exercises in this Course will enable you to recognize different stages in developing a class diagram which includes identify the objects and classes in the system and their attributes, constructing a class Diagram and writing a data dictionary to support the class diagram.
