SO MUCH DATA

SQL (Structured Query Language)

NoSQL (Not only SQL)

Relational Database (MySQL)

Document-Oriented Database (MongoDB)Column Oriented (Cassandra)

Key Value Stores (Redis, Riak)

Graph Database (Neo4j)

Let’s try it with a graph database...

Cypher - a graph query language

๏a pattern-matching query language

๏declarative grammar with clauses (like SQL)

๏aggregation, ordering, limits

๏create, read, update, delete, match

// create a node create (astronaut:Astronaut {name:"Pernilla", age: 28}),(target:Planet {planet:"Mars"}),

(mission:Mission {mission:"Mission to Mars"});

// find nodes match to node 1,2,3 MATCH (astronaut)-[:PARTICIPATES_IN] ->(mission)-[:TO]->(Planet:planet) where planet.planet = "Mars" RETURN astronaut.name
