"Dove sono i tuoi vertici e di cosa stanno parlando?" by Roberto Franchini OrientDB unisce la potenza di un database a grafo con la flessibilità di un document database creando il primo database multi-modello. Il talk esplora le funzionalità avanzate di ricerca geo-spaziale e full-text di OrientDB basate su Lucene. I due modelli di interrogazione, completamente integrati nel linguaggio SQL di OrientDB, aprono possibilità di analisi avanzate per dati geolocalizzati e testi non strutturati.

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

8. Definition
“A graph database is any
storage system
that provides
index-free adjacency”
- Marko Rodriguez
(author of TinkerPop Blueprints)

the Relational Model,
but who knows the
Graph one?

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

21. Searching for
something

22. Index
A Vertex is just a Document
We can define indexes on fields
CREATE CLASS User EXTENDS V
CREATE PROPERTY User.userId LONG
CREATE INDEX User.userId ON User(userId) UNIQUE
SELECT FROM User WHERE userId = 1024

23. What?
Ok, but my Users can describe themselves with
free text. How can I find users describing
themselves as programmes?
CREATE PROPERTY User.description STRING
CREATE INDEX User.description
ON User(description) FULLTEXT ENGINE LUCENE
SELECT FROM User
WHERE description LUCENE “programmer”

24. 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 OPoint
CREATE 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
