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.
