Design Patterns Boot Camp II

Eric Freeman
Elisabeth Robson

Design Patterns Bootcamp II is a follow on course for those who have taken the Design Patterns Bootcamp course or have equivalent experience with Design Patterns and object-oriented programming. The course picks up where Bootcamp I left off and continues our exploration of the Gang of Four patterns. By the end of the course we will have covered all the GoF Structural and Creational patterns (along with a fair number of Behavioral patterns).

Design patterns are crucial for building object-oriented software that is reliable, extensible and resilient to change. In a company setting, patterns help teams to move faster and avoid common miscommunication in a development effort.

What you'll learn-and how you can apply it

By the end of this live, hands-on, online course, you’ll understand::

  • More patterns from the core patterns defined in the original design patterns catalog, Design Patterns: Elements of Reusable Object-Oriented Software (by the “Gang of Four”).
  • More ways to think about how to incorporate design principles into software design.

And you’ll be able to:

  • Communicate more efficiently with co-workers using a broad design pattern vocabulary.
  • Draw on a broad set of proven ideas to solve software design problems.
  • Use more patterns in their everyday software design work.

This training course is for you because...

  • You are a programmer with some experience using an object-oriented programming language, you have taken Design Patterns Bootcamp I (or equivalent) and you want to continue your study of the core design patterns.
  • You are a software designer/architect with some experience using an object-oriented programming language and you want to build software that more flexible and maintainable, and communicate better with your team.
  • You are an engineering manager supervising a team of programmers using object-oriented programming languages and you need to learn how your team can use patterns in the software design process.
