1 like221 views
The document discusses the significance of GraphDB and its role in the evolution of multi-model NoSQL databases, particularly at the DevDay Napoli event. It emphasizes the advantages of graph databases in managing relationships efficiently compared to traditional relational databases, highlighting performance improvements and various application scenarios. Additionally, it outlines the features and benefits of OrientDB, a true multi-model database, including security, scalability, and user-friendly design.

- 10. #OrientDB - @ldellaquila DevDayNapoli Why do most NoSQL products avoid managing relationships?

- 14. #OrientDB - @ldellaquila DevDayNapoli This is why the database query performance suffers as the database increases in size O(Log N)

- 16. #OrientDB - @ldellaquila DevDayNapoli Solution: Graph Database!

- 20. #OrientDB - @ldellaquila DevDayNapoli Luigi Rome Visited year: 2016 An Edge connects only 2 vertices Use multiple edges to represent 1-N and N-M relationships Worked year: 2016 1-N and N-M Relationships
- 21. #OrientDB - @ldellaquila DevDayNapoli Congrats! This is your diploma in «Graph Theory»
- 22. #OrientDB - @ldellaquila DevDayNapoli How does a true* Graph Database manage relationships? *a “Graph” layer on top of a DBMS doesn’t qualify as a true GraphDB
- 23. #OrientDB - @ldellaquila DevDayNapoli Luigi Rome Visited year: 2015 #13:55 #15:99 Each element in the Graph has own immutable Record ID #22:11 (Edge) (Vertex) (Vertex) Each element in the Graph has own immutable Record ID Each element in the Graph has own immutable Record ID
- 24. #OrientDB - @ldellaquila DevDayNapoli Connections use persistent pointers Luigi Rome Visited on: 2015 #13:55 #15:99out = #22:11 in = #22:11 #22:11 (Edge) (Vertex) (Vertex) out = #13:55 in = #15:99

- 27. #OrientDB - @ldellaquila DevDayNapoli A Graph Database creates the relationship just once (when the edge is created) VS RDBMS computes the relationship every time you query a database
- 28. #OrientDB - @ldellaquila DevDayNapoli When you move from a RDBMS to a Graph Database you jump from a O(log N) speed to a near O(1) With a Graph Database, the traversing time is not affected by database size! This is huge in the BigData age
- 29. #OrientDB - @ldellaquila DevDayNapoli No costs to traverse relationships: • Recommendation engines • Social Applications • Spatial Apps • Master Data Management • Information Clustering John Thriller Comedy Pulp Fiction Mr Bean Theater B Theater A Theater C NYC San Josè Lives in Likes
- 30. #OrientDB - @ldellaquila DevDayNapoli So the Graph Model Is the only solution to efficiently manage relationships But what about data complexity? And data consistency? And scaling?
- 31. #OrientDB - @ldellaquila DevDayNapoli RelationshipsComplexity> Data Complexity > Relational Key Value Column Graph Document First Generation NoSQL
- 33. #OrientDB - @ldellaquila DevDayNapoli RDBMS Key/Value Store Document Database Graph Database Application ETL - No standard between NoSQL products - Multiple vendors = multiple skills - ETL + synchronization code is costly to write and maintain - Performance and Reliability is hard to predict

- 36. #OrientDB - @ldellaquila DevDayNapoli GraphDocument Object Key/Value Multi Model represents the intersection of multiple models in just one product - Just one product to learn and maintain - Just one vendor relationship to manage - No ETL, no synchronization required - Performance and Reliability is easy to test from the beginning What’s Multi-Model DBMS?
