Which one is NOT correct about GraphDB?

• It is a NoSQL database

• Organizes data in the form of a graph

• It is required to design schema before start development

• Edges can store properties

Which ones is NOT a types of NoSQL?

• Document-oriented

• None of these

• Column store

• Graph database

Which one is NOT an advantage of Neo4j?

• Rest API

• Embedded Server

• Has limitation on # of nodes or relationships

• All of the above

What query language is used in Neo4j?

• Rego

• SQL

• RDQL

• Cypher

Which one is a tool used in Neo4j?

• Browser

• All of the above

Can a Node contain more than 1 property?

• Yes

• No

• WHERE p.born >= 1970 AND p.born < 1980

• WHERE 1970 <= p.born < 1980

• WHERE 1970 < p.born <= 1980

• WHERE p.born IN [1970,1971,1972,1973,1974,1975,1976,1977,1978,1979]

•    MATCH(p:Person {name: “Ryoki Inoue”}) –[:WROTE]->(b:Book)

  RETURN b

•   MATCH(p:Person) –[:WROTE]->(b:Book) WHERE name = “Ryoki Inoue”

  RETURN b

• MATCH(p)-[:WROTE]->(b)

  WHERE p.name = “Ryoki Inoue”

  RETURN b

• MATCH(b)< –[:WROTE]- (p:Person {name: “Ryoki Inoue”}

  RETURN b

Suppose our graph has a Genre node for Folk and a Book node for Magia Cigana. How do we create the IN_GENRE relationship between these two nodes?

              MERGE (g:Genre {name: ‘Folk’}) __________ (b:Book {title: ‘Magia Cigana})

• –[IN_GENRE]->

• –[IN_GENRE]->

• <–[:IN_GENRE]-

• –[IN_GENRE]-
