 ===== Strategies =====
-  * Apply the [[patterns:Dependency Inversion]] Pattern
-  * Apply other forms of [[glossary:dependency inversion]]
-  * Have an ''interface'' type for every class
-  * Declare only ''interface'' types so that an object variable generally has an ''interface'' as static type and a concrete class as dynamic type
-===== Caveats =====
-It is normally not helpful to apply DIP to [[patterns:value objects]].
-Furthermore note that applying [[patterns:dependency inversion]] pattern (see [[#strategies]]) introduces an abstraction. FIXME explain Super-A vs. ReqByB
-See section [[#contrary principles]].

 ==== Generalizations ====
-  * [[Low Coupling]] (LC): LC aims at reducing the dependencies to other modules. One way to do so is to only depend on abstractions. DIP is about this aspect.
 ==== Specializations ====
 ==== Contrary Principles ====
-  * [[More Is More Complex]] (MIMC): DIP demands introducing abstractions, especially abstract classes or interfaces.
 ==== Complementary Principles ====
-  * [[Model Principle]] (MP): DIP demands having abstractions. MP tells how these abstractions can look like.
