After understanding the common terms in Gremlin, Cypher, and nGQL, let's take a look at the general syntax of these graph query languages.
In September 2019, Graph Query Language is accepted as a new database query language in a vote by the International SQL Standards Committee. The unification of GQL takes time.
In this post, we’ve selected some mainstream graph query languages and compared the CRUD usage in these languages respectively.
Gremlin is a graph traversal language developed by Apache TinkerPop and has been adopted by a lot of graph database solutions. It can be either declarative *or *imperative.
Supported graph databases: Janus Graph, InfiniteGraph, Cosmos DB, DataStax Enterprise(5.0+) and Amazon Neptune.
Cypher is a declarative graph query language that allows expressive and efficient data querying in a property graph.
The language was designed with the power and capability of SQL. The keywords of the Cypher language are not case sensitive, but attributes, labels, relationship types and variables are case sensitive.
Supported graph databases: Neo4j, AgensGraph and RedisGraph
Nebula Graph introduces its own query language, nGQL, which is a declarative, textual query language like SQL, but designed for graphs.
The keywords of the nGQL language are case sensitive and it support statement composition so that there’s no need for statement embedding.
Support graph databases: Nebula Graph
SQL stands for Structured Query Language. SQL is a scripting language expected to store, control, and inquiry information put away in social databases. The main manifestation of SQL showed up in 1974, when a gathering in IBM built up the principal model of a social database. The primary business social database was discharged by Relational Software later turning out to be Oracle.

This article will introduce the concepts and topics common to all programming languages, that beginners and experts must know!
In this article, take a look at the Nebula Graph source code and see a sample graph query. When I saw the Nebula Graph code repository for the first time, I was so shocked by its huge size that I didn’t know how to dig into the source code.
Although we still talk about programming as a standalone career, the dominance of technology in our lives makes it clear that coding is much more than a career path. In my opinion, computer science is more than a college major or a high-paid job; it’s a skill, essential for thriving in a modern-day economy. Whether you work in healthcare, marketing, business, or other fields, you will see more coding and have to deal with a growing number of technologies throughout your entire life.
