OrientDB is a multi-model NoSQL database that supports document, graph, and object models. It provides ACID transactions and can scale horizontally. This document discusses deploying OrientDB on AWS for high availability using replication across multiple master nodes and auto-scaling. It provides examples of using SQL and graph queries with OrientDB and programming interfaces for many languages.

6. SQL!

7. 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”)

8. 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
