Entity Component System

Entity-component-system (ECS) is a software architecture Pattern that separates the functionality into individual components that are mostly independent of one another. Composition is used instead of inheritance. The entity is a general purpose object. Usually, it only consists of a unique id and a container. The component consists of a minimal set of data needed for a specific purpose. Systems are single purpose functions that take a set of entities which have a specific component (or set of components) and update them. A typical application of ECS is in Computer Game-s design when there are many type of objects with many type of attributes. Instead of using a complex inheritance hierarchy of object types, entities are used with components. http://en.wikipedia.org/wiki/Entity_component_system
