# What is REST?
REST stands for [**Representational State Transfer**](https://www.ics.uci.edu/~fielding/pubs/dissertation/top.htm). It was designed in a PhD dissertation and has gained some popularity as the new web-service standard. Many developers have praised it as a much better standard than SOAP (which we will not describe here).

At the most basic level, each CRUD operation is mapped to an HTTP method in REST:



* **Create:** `POST`
* **Read:** `GET`
* **Update:** `PATCH`
* **Delete:** `DELETE`

The transport mechanism is assumed to be HTTP, but the message contents can be of any type, usually XML or JSON.

The JSR community has designed the JAX-RS API for building RESTful Java web services, while
Groovy and Scala both have some built-in support for XML and JSON and various ways of building web services.

This lesson gives an overview of RESTful.
