COMP61532: Pattern-based Software Development (2012-2013)
A software pattern is ?a solution to a recurring problem in a given context? (Grady Booch). 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; like other patterns they have names (e.g. Composite, Proxy) which form a language for communication between Software Engineers. Since the GoF book, many other design patterns have been identified.
The use of patterns spread rapidly from design to all other aspects of software development, so nowadays there are patterns for coding, testing, requirements capture, software architecture, and so on. More recently some organisations have focussed on documenting software patterns from a business rather than a technical perspective. IBM?s ?patterns for e-business? project is probably the most comprehensive and useful of such efforts.
This 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.

Academic knowledgeThe notion of a pattern and of different kinds of software patterns;
The relationship between business requirements and e-business application architectures;
IBM Patterns for e-business as solutions for e-business application system design;
Commonly used software patterns, especially design patterns
The use of patterns for designing an e-business system based on a real world case study.

Demonstrate a competence in applying patterns to the e-business design.
Demonstrate competence in selecting and applying design patterns to construct software
Subject practical skillsApply the pattern approach to two practical situations, one focussing on e-business patterns and one on design patterns.
