Layered Architecture

Protocol, service, and interface

Application layers

Traditional three layers vision.

• Data.

• Interface

• Processing

MVC - Model, View, Controller

Example: Search Engine

Object-Based and Service Oriented Architectures

• Data encapsulation.

• Object implementation details are hidden by the interface.

• When a client binds itself to a distributed object, an object's interface implementation is loaded - proxy.

• A complementary entity called a skeleton appears on the server side.

Resources Oriented Architectures

Operation	Description
PUT	Creates a resource
GET	Access a resource's state
DELETE	Destroys a resource
POST	Modifies a resource, it's state is replaced

Resources are identified by a unique schema of identifiers.

All the services offer the same interface.

All the messages are self-contained.

After an operation execution, the component forgets everything about the called resource.
