Layered Architecture
Layered Architecture is a software design pattern that organizes an application into distinct horizontal layers, each with a specific responsibility, such as presentation, business logic, and data access. It promotes separation of concerns by ensuring that each layer only interacts with adjacent layers, typically through well-defined interfaces. This pattern is widely used in enterprise applications to improve maintainability, testability, and scalability.
Developers should use Layered Architecture when building complex applications that require clear separation between user interface, business rules, and data persistence, such as in web or desktop applications. It is particularly valuable in team environments where different developers can work on separate layers without interference, and it facilitates easier testing and future modifications by isolating changes to specific layers.
