REST

REST (Representational State Transfer) is an architectural style for developing network services based on the principles of simplicity, flexibility, and scalability.

The main functions of REST:

Stateless:

Each request to a REST server must contain all the information necessary to process it, regardless of the state of previous requests. This makes REST systems fault-tolerant and error-resistant.

Homogeneous resources:

All resources in a REST system are represented as homogeneous resources that can be manipulated using standard HTTP methods (GET, POST, PUT, DELETE). This makes REST interfaces easy to learn and use.

Caching:

REST systems support caching, which allows clients to keep copies of retrieved data for reuse. This can significantly improve performance and reduce server load.

Layering:

REST systems can be divided into layers, which makes them flexible and scalable.

Interconnection of resources:

REST systems use URIs (Uniform Resource Identifier) to identify resources and describe their relationships. This makes REST interfaces clear and understandable.
