Object-oriented systems are difficult to implement and develop using the concept of reuse is even more difficult. Find the persistence of objects, define interfaces and inheritance hierarchy and establish the key relationship between classes. The design should be specific to a problem, but otherwise it should be general problems and to meet future requirements. You certainly will not want to redesign the model or at least want to minimize the impact of changes.
