Un approccio pratico

Gabriele De Carli - @Gabber_84 Luigi Dell’Aquila - @ldellaquila

Cos’è Orient DB?

• NoSQL*

• Document/Graph Database

• REST/JSON

• Scalable

• Multi Platform

• ACID Transaction

Il modello dei dati

• Database

• Cluster

• Class - Inheritance• Vertex/Edge• Document

• Schema• Schemaful• Schemaless• Schema-mixed

Interfacce di interrogazione

• HTTP REST

• Native• Java• Scala• JavaScript• PHP• C• Ruby• .NET• Python• Node.js• Clojure

• Tinkerpop Blueprints compliant

NoSQL ma…

SQL!

Esempi

CREATE CLASS PERSON;

INSERT INTO PERSON (NAME, SURNAME) VALUES (“MARIO”, “ROSSI”);

SELECT * FROM PERSON WHERE SURNAME = “ROSSI”;

SELECT NAME, SURNAME, ADDRESS.CITY.REGION.COUNTRY FROM PERSON WHERE SURNAME = “ROSSI” AND ADDRESS.CITY.REGION.COUTRY.CONTINENT.NAME = “EUROPE”;

CREATE CLASS PERSON EXTENDS V;

CREATE CLASS FRIEND EXTENDS E;

CREATE VERTEX PERSON SET NAME = “MARIO”, SURNAME = “ROSSI”

CREATE VERTEX PERSON SET NAME = “MARCO”, SURNAME = “VERDI”

CREATE EDGE FRIEND FROM #10:1 TO #10:2

CREATE EDGE FRIEND FROM (SELECT FROM PERSON WHERE SURNAME = “ROSSI”) TO (SELECT FROM PERSON WHERE SURNAME = “VERDI”)

Esempi

SELECT FROM CITY WHERE COUNTRY.NAME.substring(1,3).toUpperCase() = “TAL”

SELECT FROM AGENDA WHERE EMAIL MATCHES '\bA-Z0-9._%+-?+@A-Z0-9.-?+\.A-Z?{2,4}\b’

SELECT MAX(INCOMING) AS MAX_INCOMING, MAX(COST) AS MAX_COST FROM BALANCE

In più (in ordine sparso)

• Supporto Transazionale

• Javascript nativo

• Funzioni

• TinkerPop - Gremlin

• Java Object API

• Local/remote/embedded mode

• Veloce! 150.000 record/secondo (flat, no index)
