WHAT_ARE_THE_DRAWBACKS_FOR_LAYERS??$

It is often necessary to pass data through many layers, which can slow performance significantly

Layers support information hiding

Multi-layered programs can be hard to debug because operations tend to be implemented through a series of calls across layers

In particular, layers have which of the following characteristics?

Layers doesn‚Äö√Ñ√∂‚àö√ë‚àö¬•t support information hiding

Layers are by definition highly cohesive, thus satisfying the Principle of Cohesion

Layers doesn‚Äö√Ñ√∂‚àö√ë‚àö¬•t support information hiding

Layers are constrained to use only above layers

Which of the following is true with respect to layered architecture?

Each layer is allowed to depend on the layer above it being present and correct

A layer may call other layers above and below it, as long as it uses them

What is Relaxed Layered Style?

Each layer can be constrained to use only the layer directly below it

Sometimes this constraint is relaxed slightly to allow each layer to use all the layers below it
