Especially when written “Entity Component System”, due to an ambiguity in the English language, a common interpretation of the name is that an ECS is a system comprising entities and components. For example, in the 2002 talk at GDC, [ 1 ] Scott Bilas compares a C++ object system and his new custom component system.
The components are details of the message, for example the message's text "Hello, world!" or perhaps the message's font or color. The system in this case is the entity-renderer, that renders messages to the screen. In this case, the system looks only at the text component of the entity and not other entity components.
A (software) design pattern is a general solution to a common problem in software design. It is a description or template for how to solve a problem, that can be used in different situations.
The entity–control–boundary approach finds its origin in Ivar Jacobson's use-case–driven object-oriented software engineering (OOSE) method published in 1992. [1] [2] It was originally called entity–interface–control (EIC) but very quickly the term "boundary" replaced "interface" in order to avoid the potential confusion with object-oriented programming language terminology.
The system can be designed visually with the Unified Modeling Language (UML). Each component is shown as a rectangle, and an interface is shown as a lollipop to indicate a provided interface and as a socket to indicate consumption of an interface. Component-based usability testing is for components that interact with the end user.

Component. is the abstraction for all components, including composite ones; declares the interface for objects in the composition (optional) defines an interface for accessing a component's parent in the recursive structure, and implements it if that's appropriate; Leaf. represents leaf objects in the composition; implements all Component ...
