Object-Oriented Analysis and Design (OOAD) is a process of identifying the needs of a software project and then laying out those specifications in a readable model. Design Patterns are an extension of these skills that create more maintainable and robust code. Using well-known, proven patterns that either stand-alone or build from one to the next, designers are able to further define the specifications of the project, optimizing quality and time spent on developing the project by programmers.

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.
