In software development, frontend refers to the presentation layer that users interact with, while backend involves the data management and processing behind the scenes. In the client–server model, the client is usually considered the frontend, handling user-facing tasks, and the server is the backend, managing data and logic.
ARCADIA, a model-based engineering method for systems, hardware and software architectural design. ARCADIA ( Arc hitecture A nalysis & D esign I ntegrated A pproach) is a system and software architecture engineering method based on architecture-centric and model-driven engineering activities.
To support React's concept of unidirectional data flow (which might be contrasted with AngularJS's bidirectional flow), the Flux architecture was developed as an alternative to the popular model–view–controller architecture.
Capella was created by Thales in 2007, and has been under continuous development and evolution since then. The objective is to contribute to the transformation of engineering, providing an engineering environment which approach is based on models rather than focused on documents, piloted by a process, and offering, by construction, ways to ensure effective co-engineering.
Analogous to a façade in architecture, it is an object that serves as a front-facing interface masking more complex underlying or structural code. A facade can: improve the readability and usability of a software library by masking interaction with more complex components behind a single (and often simplified) application programming interface ...
The model is an interface defining the data to be displayed or otherwise acted upon in the user interface. The view is a passive interface that displays data (the model) and routes user commands to the presenter to act upon that data. The presenter acts upon the model and the view. It retrieves data from repositories (the model), and formats it ...
The observer pattern may be used in the absence of publish-subscribe, as when model status is frequently updated. Frequent updates may cause the view to become unresponsive (e.g., by invoking many repaint calls); such observers should instead use a timer. Instead of becoming overloaded by change message, the observer will cause the view to ...
The reactor software design pattern is an event handling strategy that can respond to many potential service requests concurrently.The pattern's key component is an event loop, running in a single thread or process, which demultiplexes incoming requests and dispatches them to the correct request handler.
