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.

Many modern languages, including C++ and Java, provide a "protected" access modifier that allows subclasses to access the data, without allowing any code outside the chain of inheritance to access it. The composite reuse principle is an alternative to inheritance. This technique supports polymorphism and code reuse by separating behaviors from ...
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.
Resources, events, agents (REA) is a model of how an accounting system can be re-engineered for the computer age.REA was originally proposed in 1982 by William E. McCarthy as a generalized accounting model, [1] and contained the concepts of resources, events and agents (McCarthy 1982).
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.
Structured systems analysis and design method (SSADM) is a systems approach to the analysis and design of information systems. SSADM was produced for the Central Computer and Telecommunications Agency , a UK government office concerned with the use of technology in government, from 1980 onwards.
