Layered architecture in software development

Layered Architecture is a widely used design pattern in software development that organizes an application into distinct layers, each with a specific responsibility. This structure improves maintainability, scalability, and testability by enforcing a clear separation of concerns.

Common Layers in a Layered Architecture

A typical layered architecture consists of the following layers:

Advantages of Layered Architecture

• Separation of Concerns: Each layer has a distinct role, making code easier to manage.
• Scalability: Components can be modified independently without affecting other layers.
• Reusability: Business logic and data access code can be reused across different applications.
• Testability: Isolating layers simplifies unit testing and debugging.

Layered Architecture is a robust design pattern that enhances the structure and maintainability of software applications. It is widely used in enterprise applications, including ASP.NET, Java, and Node.js projects, ensuring a clean and scalable development approach.
