Design Patterns

A design pattern is often posed as a question: how do we solve some design problem? However a design problem is, by its

nature, nonspecific, and rarely has a single straight-forward answer. There might be several ways to solve the same problem, some

better than others depending on the specific situation and the specific context of the problem. A design pattern is intended to share

not just solutions but a better understanding of both the problem and how it might be solved.

Firstly, patterns have a well-defined structure. This consistent layout makes it easy to browse through a collection of patterns

to find relevant help and then dive further into the material. The structure encourages the author of the pattern to think carefully about

the knowledge they're sharing, whilst making the material more consistently accessible to a reader.

Secondly, unlike a tutorial or recipe which typically guides you through a single approach to solving a problem, patterns

encourage discussion of related and complementary approaches. Design decisions are rarely clear cut, so it can be useful to

understand the context in which a decision is made and the resulting trade-offs. Communicating these nuances is how we share

knowledge rather than just fixes for a problem.
