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.
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.

[citation needed] Architecture styles typically include a vocabulary of component and connector types, as well as semantic models for interpreting the system's properties. These styles represent the most coarse-grained level of system organization. Examples include Layered Architecture, Microservices, and Event-Driven Architecture. [35] [36] [37]
Another implementation could potentially retrieve or write records to or from a file system. The DAL hides this complexity of the underlying data store from the external world. For example, instead of using commands such as insert , delete , and update to access a specific table in a database, a class and a few stored procedures could be ...
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.
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.
Example of a high-level systems architecture for a computer. A system architecture is the conceptual model that defines the structure, behavior, and views of a system. [1] An architecture description is a formal description and representation of a system, organized in a way that supports reasoning about the structures and behaviors of the system.
