WÄÄÄÄÄ
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
