Layered Architecture is a software design pattern that organizes a system into distinct layers, each with specific responsibilities. Typically, these layers include the presentation layer, business logic layer, and data access layer. This separation allows for easier maintenance, as changes in one layer can often be made without affecting others. Each layer communicates with the layers directly adjacent to it, promoting a clear structure and reducing dependencies. For example, the presentation layer interacts with the business logic layer to process user requests, while the business logic layer accesses the data layer to retrieve or store information. This modular approach enhances scalability and flexibility in software development.
