 GraphQL is an open source data query language. Unlike REST APIs, each HTTP request that is sent to a GraphQL service goes to a single HTTP endpoint. Create, read, update, and delete operations and their details are differentiated by the contents of the request. If the operation returns data, the user specifies what properties of the data that they want returned. For read operations, a JSON object is returned that contains only the data and properties that are specified. For other operations, a JSON object might be returned containing information such as a success message.

 == Implementing system service
 
-The `system` microservices are backend services that use JAX-RS. For more details on using JAX-RS, see the https://www.openliberty.io/guides/rest-intro.html[Creating a RESTful web service guide^]. These `system` microservices report system properties. GraphQL can access multiple instances of these `system` microservices and collate their information. In a real scenario, GraphQL might access multiple databases or other services.
