OverviewThis course unit will introduce students to a wide range of software patterns, with particular emphasis on design patterns and e-business patterns. As well as a theoretical understanding of patterns students will gain practical experience of applying them through laboratory case studies. Patterns capture existing best practice, and so are identified or discovered rather than invented. Software patterns first became widely known through the famous 1992 'gang of four' (GoF) book, called Design Patterns, although the notion of patterns in this sense originated with the architect Christopher Alexander in the 1970s. Design patterns are solutions to recurring software design problems.
