+# Strategy
+
+## Terminology:
+
+* Context
+* Strategy
+* Concrete Strategy
+
+## Purpose
+
+To separate strategies and to enable fast switching between them. Also this pattern is a good alternative to inheritance (instead of having an abstract class that is extended).
+
+## Examples
+
+* sorting a list of objects, one strategy by date, the other by id
+* simplify unit testing: e.g. switching between file and in-memory storage
