IEKlassen

IEKlassen is a term used in German-language programming and education materials to denote a structured set of classes used for teaching or implementing object-oriented software. The term does not refer to a single, universal standard; instead, it describes contextual class collections and taxonomies that vary by institution or project.

In software engineering contexts, IEKlassen typically describes a small family of classes designed to support modularity and reuse. Common roles include entity or data classes that model information, controller or service classes that coordinate workflows, and utility or helper classes that provide cross-cutting functionality. The taxonomy aligns with principles from object-oriented design and encourages clear interfaces and well-defined responsibilities.

In education, IEKlassen are used in introductory courses to illustrate key OO concepts such as inheritance, composition, and polymorphism. A typical learning set might include a base abstract class, one or more concrete subclasses, and interface definitions that students implement and extend. The materials often accompany exercises that simulate simple domains like a library system, a drawing tool, or a small store to demonstrate interactions among classes.

Design considerations emphasize encapsulation, low coupling, and high cohesion, with attention to testability and maintainability. Some variants promote a three-tier or layered view of classes (data, logic, presentation), while others focus on interface-driven design and dependency inversion.
