Question

How does a layered pattern make use of abstraction and encapsulation?

Answer 1

Answer and Explanation:

The ways in which a layered pattern make use of encapsulation and abstraction are as follows:

• This framework lays its focus mainly on the bundling of related functionalities inside an application into different layer that are vertically stacked over one another.
• Functionality in between each layer is related by common function or role.
• Communication in between the layers is clear and exact and is coupled loosely.
• Providing a layered structure to the application indirectly supports its maintainability and flexibility.

Encapsulation:

Since, features like data type, properties, methods or implementation while designing are not exposed at the boundary of the layer thus No assumptions are required for these features.

Abstraction:

The layered framework abstracts the entire system's view and provides adequate details for better understanding of the roles of each layer individually and the relation that exist between these layers.
