7. Software design pattern - Wikipedia

   en.wikipedia.org/wiki/Software_design_pattern

   In software engineering, a design pattern describes a relatively small, well-defined aspect (i.e. functionality) of a computer program in terms of how to write the code . Using a pattern is intended to leverage an existing concept rather than re-inventing it. This can decrease the time to develop software and increase the quality of the ...
