Cypher (query language) Cypher is a declarative graph query language that allows for expressive and efficient data querying in a property graph. Cypher was largely an invention of Andrés Taylor while working for Neo4j, Inc. (formerly Neo Technology) in 2011.

Considering this, what is graph query language?
No more joins: An overview of Graph database query languages. They allow you to store data as entities (nodes) and relationship (edges), and allow you to query the data as a graph. Queries written against graph databases are closer to how the data is modeled than other query languages.
Also, what are the two different categories of query language? Database query languages have at least two subsets of commands: Data Definition Language (DDL) and Data Manipulation Language (DML).

When would you use a graph database?
Graph databases are very good at traversing relationships between small data entities, but not ideally suited to store a lot of properties on a single node or large values in those properties.How do you create a relationship between nodes in neo4j?
Create two nodes in the database using the Neo4j database connection. Use the 'Labels' name-value pair argument to specify the label Person for each node. label = 'Person'; startnode = createNode(neo4jconn,'Labels',label); endnode = createNode(neo4jconn,'Labels',label);IS NOT NULL neo4j?
In Neo4j, since there is no table schema or equivalent to restrict possible properties, non-existence and null are equivalent for node and relationship properties. That is, there really is no such thing as a property with a null value; null indicates that the property doesn't exist at all.What are the different types of queries?
