Pablo’s Topic of the Month – November: Design Patterns

Pablo’s Topic of the Month – November: Design Patterns

Back in April, we announced we would be doing a PTOM on Design Patterns. It turned out that April was a busy month for all of us and we didn’t live up to our announcement. I think we’re going to claim it as a sad April fools joke. During the course of this month we will revisit our previous topic with the exception that the patterns will not just be patterns from ‘Design Patterns: Elements of Reusable Object-Oriented Software’ (Addison-Wesley. ISBN 0-201-63361-2) , but from various sources which we believe are relevant to the types of programs being written today.

What is a Design Pattern?

A Design Pattern is exactly what it sounds like. It’s a design that can be applied over and over again, forming a pattern. The Wikipedia page for Design Patterns describes one as

a general reusable solution to a commonly occurring problem in software design. A design pattern is not a finished design that can be transformed directly into code. It is a description or template for how to solve a problem that can be used in many different situations.

By using Design Patterns, we can better standardize our designs makes them easier to understand. Design Patterns give us a common vocabulary in which to use in communicating software designs. Without them, we would have a difficult time in explaining and documenting our ideas.

We will update this area with links to the posts as they happen.
