Description: The layered approach is a method of organizing software architecture that divides a system into distinct layers, each with specific responsibilities. This approach allows for the separation of concerns, meaning that each layer deals with a particular aspect of the system, such as presentation, business logic, or data access. This separation facilitates maintainability and scalability of the software, as changes in one layer do not directly affect others. Additionally, it promotes component reuse, as layers can be developed and tested independently. Typical layers include the presentation layer, which interacts with the user; the business logic layer, which contains the business rules and processes; and the data access layer, which handles interaction with databases or external services. This approach not only improves code organization but also allows for better collaboration among development teams, as each group can focus on a specific layer without interfering with others’ work. In summary, the layered approach is fundamental for building robust and sustainable software systems across various technology domains, facilitating their evolution over time.
