This advanced Object-Oriented course provides software architects and designers with skills to create high quality object-oriented designs exhibiting improved flexibility, reduced maintenance costs, and with increased understanding of the resulting code. Participants learn more than 30 object-oriented patterns, including the 23 micro-architectures in "Design Patterns: Elements of Reusable Object-Oriented Software", by Gamma, Helm, Johnson, and Vlissides (the gang-of-four, or GoF book). Application examples and code snippets are provided to illustrate the patterns and the rationale for using that pattern in a given situation.

Audience

Software architects and designers requiring advanced design skills.

Prerequisites

Object-Oriented Analysis & Design-UML or equivalent experience. At least 6 months experience programming with an object-oriented programming language.

Course duration

4 Days
