Pattern (glossary)

(1) An expression of an observed regularity. (Alexander 1979)

(2) A representation of similarities in a set or class of problems, solutions, or systems. (Alexander 1979)

(3) Each pattern describes a problem which occurs over and over again in our environment, and then describes the core of the solution to that problem, in such a way that you can use this solution a million times over, without ever doing it the same way twice. (Alexander 1979)
