softwarelaagrisüsteem

Softwarelaagrisüsteem, often translated as software layering system or layered software architecture, refers to a design principle in software engineering where functionalities are organized into distinct horizontal layers. Each layer has specific responsibilities and interacts only with the layer immediately above or below it. This separation of concerns promotes modularity and maintainability in software development.

The typical layers in such a system include the presentation layer, which handles user interface and interaction; the business logic layer, containing the core application logic and business rules; and the data access layer, responsible for managing data storage and retrieval. Additional layers, such as a domain layer or a service layer, can be incorporated depending on the complexity of the application.

By adhering to a layered architecture, developers can modify or update one layer without significantly impacting other layers, as long as the interfaces between them remain consistent. This makes the system easier to understand, test, and extend over time. It also allows different teams to work on different layers concurrently. Common examples of software layered systems include web applications, enterprise software, and operating systems. The principle is a fundamental concept in building robust and scalable software.
