Author Description

The aim of this unit is to provide the tools and background necessary to move from the abstract representation of a system as a UML model, to its concrete (nuts and bolts) implementation and installation (deployment) ready for use. This unit looks at how to ensure that design requirements are reflected in the implemented codes, looking in particular at how contracts specified during design may be implemented in Java. It also looks at how inheritance can affect the contracts. Finally, the notion of components is introduced. This can be used to increase reuse and to structure a system for both deployment and maintenance reasons.
