GraphQL is a data query and manipulation language for APIs that allows a client to specify what data it needs ("declarative data fetching"). A GraphQL server can fetch data from separate sources for a single client query and present the results in a unified graph . [ 2 ]
In September 2019 a proposal for a project to create a new standard graph query language (ISO/IEC 39075 Information Technology — Database Languages — GQL) [3] was approved by a vote of national standards bodies which are members of ISO/IEC Joint Technical Committee 1(ISO/IEC JTC 1).
GraphQL is implemented to allow users to query TerminusDB projects in such a way that deep linking can be discovered. [24] WOQL (web object query language) is a datalog-based query language. It allows TerminusDB to treat the database as a document store or a graph interchangeably, and provides query features to make relationship traversals easy ...
GraphQL: an open-source data query and manipulation language for APIs. Dgraph implements modified GraphQL language called DQL (formerly GraphQL+-) Gremlin: a graph programming language that is a part of Apache TinkerPop open-source project [49] SPARQL: a query language for RDF databases that can retrieve and manipulate data stored in RDF format
Cypher is a declarative graph query language that allows for expressive and efficient data querying in a property graph. [1]Cypher was largely an invention of Andrés Taylor while working for Neo4j, Inc. (formerly Neo Technology) in 2011. [2]
Graph query languages, such as Cypher Query Language, GraphQL, and Gremlin, are designed to query graph databases, of which RDF data stores are an example. [ 13 ] The Topic Map Query Language (TMQL) [ 14 ] is a query language for topic maps , a data representation similar to but more general than RDF.
GraphQL is a specific query and API language. It is the focus of tailored testing techniques. It is the focus of tailored testing techniques. Search-based test generation yields good results to generate test cases for GraphQL APIs.
From 2016 the Meteor Development Group (the open source organisation powering Meteor) started working on a new backend layer based on GraphQL to gradually replace their pub/sub system, largely isolated in the whole node.js ecosystem: the Apollo framework.
