Data by itself has little value, it’s the relationship between data that gives it

incredible value

Data and relationships

Definition

“A graph database is any storage system that provides

index-free adjacency” - Marko Rodriguez (author of TinkerPop Blueprints)

Every developer knows the Relational Model, but who knows the

Graph one?

Back to school: Graph Theory crash course

Vertices and Edges can have properties

Vertices are directed

An Edge connects only 2 vertices

Use multiple edges to represent 1-N and N-M relationships

General purpose solution: • JSON • Schema-less • Schema-full • Schema-hybrid • Nested documents • Rich indexing and querying • Developer friendly

Searching for something

IndexA Vertex is just a Document

We can define indexes on fields

CREATE CLASS User EXTENDS VCREATE PROPERTY User.userId LONGCREATE INDEX User.userId ON User(userId) UNIQUE

SELECT FROM User WHERE userId = 1024

What?Ok, but my Users can describe themselves with

free text. How can I find users describing themselves as programmes?

CREATE PROPERTY User.description STRINGCREATE INDEX User.description ON User(description) FULLTEXT ENGINE LUCENE

SELECT FROM User WHERE description LUCENE “programmer”

From where?Users write articles with geo localisation data

inside. I want all the article posted from the Rome area

CREATE CLASS Article EXTENDS V CREATE PROPERTY Article.geo EMBEDDED OPointCREATE INDEX Article.geo ON Article (geo) SPATIAL ENGINE LUCENE

SELECT * FROM Article WHERE ST_WITHIN(geo, ST_Buffer( ST_GeomFromText(‘POINT(12.5113300 41.8919300)'), 1)) = true
