What are the benefits of multi layer architecture?
Advantages
- The framework is simple and easy to learn and implement.
- There is reduced dependency because the function of each layer is separate from the other layers.
- Testing is easier because of the separated components, each component can be tested individually.
- Cost overheads are fairly low.
