Which is the most fundamental requirement of a REST based architecture?
RESTFul Client-Server This is the most fundamental requirement of a REST based architecture. It means that the server will have a RESTful web service which would provide the required functionality to the client. The client send’s a request to the web service on the server.
What’s the difference between a rest and a RESTful service?
A Restful is an advanced form of web exchange server that shares any other documents or JSON to develop any new applications. The REST represents the Representational State Transfer, which uses an architectural pattern for developing new web services and implementing that architectural pattern; RESTful services are implemented.
What are the six guiding constraints of RESTful system?
Six guiding constraints define a RESTful system. These constraints restrict the ways that the server can process and respond to client requests so that, by operating within these constraints, the system gains desirable non-functional properties, such as performance, scalability, simplicity, modifiability, visibility, portability, and reliability.
What are some examples of RESTful Web Services?
Over the past couple of years, this standard has become quite popular. And is being used by many of the popular websites around the world which include Facebook and Twitter. REST is a way to access resources which lie in a particular environment. For example, you could have a server that could be hosting important documents or pictures or videos.

Restful Web Service, expose API from your application in a secure, uniform, stateless manner to the calling client. The calling client can perform predefined operations using the Restful service.
What is the purpose of the service layer?
The service layer can also be used to define authorization policies that each operation may require. In conclusion, the service layer is where to place any business logic operation that one or more controllers need, except for (de)serialization.
Why do we need a service layer for daos?
In fact, the two APIs may perform the same operations. Defining a layer between DAOs and Controllers increment the level of decoupling and make each controller function easier to manage and read. The service layer can also be used to define authorization policies that each operation may require.
