Design Patterns in Practice

A Pattern-Based Approach to Effective Application Design. Many developers go through their career without being familiar with design patterns.
This course is designed to equip developers with the confidence and ability to apply design patterns within the applications that they develop. Patterns are introduced
through real world problems that need to be solved, and students are encouraged to solve the problem after which they are introduced to a design pattern that could be
used to address the requirement. This approach to teaching design patterns works really well as the patterns are not learned in some sterile way, but in the context of
real software problems that are solved through appropriate pattern application. The course is not specific to any programming language or platform, and would be very
beneficial to .NET and Java developers who wish to improve and develop their design skills.

Duration: 1 day

Who is it for: Architects, designers and developers who wish to improve their design skills through appropriate use of proven patterns.

Layout: This workshop consists of lectures, demonstrations, exercises and discussions.
