What is a strictly layered pattern, provide an example of its usage.

Answer and Explanation:

A strictly layered pattern can be defined as an approach that restricts the interaction of the components in a layer in the application.

It limits the interaction of the layer components to the adjacent layers or the layer that lies just below the the layer itself.

For Example:

If the application is layered as the Fig 1. shows

Then accordingly, Layer K will interact with the layer K - 1 and Layer K - 1 will interact only with the layer K - 2 and so on.
