OrientDB: a Document-Graph Database ready for the Cloud - Dell'Aquila
Download as PPTX, PDF3 likes917 views
This document summarizes a presentation about OrientDB, a document-graph database that supports both graph and document data models. It can represent complex, linked data through graphs and objects rather than tables and rows. OrientDB also supports features like JavaScript extensions, multi-master replication, and horizontal scaling on cloud infrastructures. The presentation provides examples of OrientDB's capabilities and discusses how it can more efficiently store and query certain types of data compared to relational databases.

- 11. ROME 11-12 april 2014 - Luigi Dell’Aquila These are GRAPHS!
- 12. ROME 11-12 april 2014 - Luigi Dell’Aquila And sometimes Representing them in tables Can be difficult And Inefficient
- 13. ROME 11-12 april 2014 - Luigi Dell’Aquila Think about it…
- 14. ROME 11-12 april 2014 - Luigi Dell’Aquila When you write your code You have to deal with Links, References, Pointers
- 15. ROME 11-12 april 2014 - Luigi Dell’Aquila When you write your code You have to deal with Collections and Maps (and dynamic data structures!)
- 16. ROME 11-12 april 2014 - Luigi Dell’Aquila When you write your code You have to deal with Nested and complex objects
- 17. ROME 11-12 april 2014 - Luigi Dell’Aquila When you write your code You have to deal with Class hierarchies, Inheritance, Polymorphism

- 19. ROME 11-12 april 2014 This is why Was born - Luigi Dell’Aquila
- 20. ROME 11-12 april 2014 - Luigi Dell’Aquila Two data models: Graph and Document
- 21. ROME 11-12 april 2014 - Luigi Dell’Aquila Classes, not Tables create class Person create class Student extends Person select from Person Polymorphic query: returns both instances of Person and Student
- 22. ROME 11-12 april 2014 - Luigi Dell’Aquila Dynamic schema create class Person insert into Person (name, surname) values (“Luigi”, “Dell’Aquila”) No need to fully specify the class structure, you can work in schemaless mode
- 23. ROME 11-12 april 2014 - Luigi Dell’Aquila Complex attributes Update person set address = { “street”: “5th Ave”, “city”: “NY” }, tags = [“developer”, “artist”, “geek”] Collections and embedded properties
- 24. ROME 11-12 april 2014 - Luigi Dell’Aquila Physical links (no Join!) Update person set address.city = (select from city where name = ‘Rome’) where name = ‘Luigi’ Select address.city.country.name from Person where name = ‘Luigi’ Dot notation instead of Join No need for foreign keys O(1) computational cost – compared to O(log N) in relational Join
- 25. ROME 11-12 april 2014 - Luigi Dell’Aquila The Graph API (TinkerPop Blueprints) Traverse out(“Friend”) from (select from Person where name = ‘Luigi’) while address.city = ‘Rome’ Find my friends network in my city (friends, firends of frineds, friends of friends of friends…) Deep traversal, no need to know in advance HOW deep
- 26. ROME 11-12 april 2014 - Luigi Dell’Aquila Every record has unique ID Select from Person {"result": [ { "@rid": "#13:0", "@class": “Person", "name": "Luigi", "surname": "Dell'Aquila", "friendOf": "#13:1" } ]}

- 29. ROME 11-12 april 2014 - Luigi Dell’Aquila Record ID (RID) = Physical position
- 30. ROME 11-12 april 2014 - Luigi Dell’Aquila Traversing relationships = Following a physical path
- 31. ROME 11-12 april 2014 - Luigi Dell’Aquila It means: • Accessing linked data is very efficient • No calculation * • Independent from cluster size ** • Deep traversal is allowed and encouraged *** * In RDMS, a Join is calculated EVERY TIME you execute a query ** RDBS use index-based optimization to speed up joins, but index access is O(log N), so it depends on data size – what about Big Data??? *** in RDMS multiple joins are inefficient (would you dare to write a query with 1000 joins?)
