The aim of this module is:- To explain common design patterns in OO development.- To provide the learner with an in-depth understanding of how to navigate through design patterns so that they can be combined in the most optimal way to solve common design problems.- To show the similarities between system designs.- To illustrate the importance of a good design approach to OO design to allow for code reuse.- To have a working knowledge of a case tool supporting UML and design patterns.
