The Graph Principle
8th Sutol Conference, November 2016
GraphDB - Definition
A graph database, also called a graph-oriented
database, is a type of NoSQL database that
uses graph theory to store, map and query
relationships.
A graph database is essentially a collection of
vertices and edges. Each vertex represents an
entity (such as a person or business) and each
edge represents a connection or relationship
between two vertices.

8th Sutol Conference, November 2016
Some GraphDBs and Frameworks
• Neo4J
• OrientDB
• Titan/Cassandra
• Tinkerpop (used here in ODA)
• Apache Lucene / Solr
8th Sutol Conference, November 2016
Who’s using GraphDBs?
• Amazon
• Google/Youtube
• Facebook, Twitter
• IBM Watson Workspace
• almost every application that offers something like
• "summarize", "assist"
• "related posts" (blogs)
• "others also bought this" (shops)
• collect relations and "likes"
• …
8th Sutol Conference, November 2016
GraphDB - Terminology
• Vertices (singular: Vertex)
• has Properties (Key-Value pairs)
• sometimes referred to as Nodes or Elements
• Edges
• Connections, Relations between Vertices
• ElementStores
• for us: NSF databases
• MetaverseIDs (GraphNSF)
• Replica + UNID (hashed)
• internal use only (don‘t care about them)
8th Sutol Conference, November 2016
Introducing:
GraphNSF
8th Sutol Conference, November 2016
GraphNSF is part of ODA
• Introduced and maintained by
• Nathan T. Freeman
• Paul S. Withers
• Uses Tinkerpop framework
• Under heavy development since ODA 2.0
• Current version is ODA 3.0
• GraphNSF is transactional
8th Sutol Conference, November 2016
GraphNSF = GraphDB in Domino
• Vertices and Edges are stored as Documents
• The data container is a NSF
• The ElementStore defines the file path to the
NSF
• An ElementStore can hold different types of
Vertices
• Usually you create one ElementStore for
each Vertex type
8th Sutol Conference, November 2016
Implementation & Data Modeling
• Vertices are defined as Interface classes
• Fields are defined as properties with Getter
and Setter
• Methods define how the Node can build
Edges to other Vertices
• Methods also return all Edges to a certain
Vertex
• All inside the NSF using ODA
8th Sutol Conference, November 2016
Init the Graph
• Define the Element Store(s)
• Add Element Store(s) to the Graph
Configuration
• Define the DFramedTransactionalGraph
object with the Graph Configuration
• Add Vertex types to Element store(s)
• Work with the Graph object
8th Sutol Conference, November 2016
Create an Edge
• Parameterize Object 1
• Get Object 2 by a unique key
• Call one of the „add“ methods of your Node
class
• Commit your changes
8th Sutol Conference, November 2016
A strategy? Add some meta data
• a most common use case is to add meta
data to existing data using Graph data
• no need to touch the original data :-)
• graph data is highly extensible (like NoSQL
is in general)

  • 5. 8th Sutol Conference, November 2016 The Graph Principle
  • 6. 8th Sutol Conference, November 2016 GraphDB - Definition A graph database, also called a graph-oriented database, is a type of NoSQL database that uses graph theory to store, map and query relationships. A graph database is essentially a collection of vertices and edges. Each vertex represents an entity (such as a person or business) and each edge represents a connection or relationship between two vertices. http://whatis.techtarget.com/definition/graph-database
  • 7. 8th Sutol Conference, November 2016 Some GraphDBs and Frameworks • Neo4J • OrientDB • Titan/Cassandra • Tinkerpop (used here in ODA) • Apache Lucene / Solr
  • 8. 8th Sutol Conference, November 2016 Who’s using GraphDBs? • Amazon • Google/Youtube • Facebook, Twitter • IBM Watson Workspace • almost every application that offers something like • "summarize", "assist" • "related posts" (blogs) • "others also bought this" (shops) • collect relations and "likes" • …
  • 9. 8th Sutol Conference, November 2016 GraphDB - Terminology • Vertices (singular: Vertex) • has Properties (Key-Value pairs) • sometimes referred to as Nodes or Elements • Edges • Connections, Relations between Vertices • ElementStores • for us: NSF databases • MetaverseIDs (GraphNSF) • Replica + UNID (hashed) • internal use only (don‘t care about them)
  • 10. 8th Sutol Conference, November 2016 Introducing: GraphNSF
  • 11. 8th Sutol Conference, November 2016 GraphNSF is part of ODA • Introduced and maintained by • Nathan T. Freeman • Paul S. Withers • Uses Tinkerpop framework • Under heavy development since ODA 2.0 • Current version is ODA 3.0 • GraphNSF is transactional
  • 12. 8th Sutol Conference, November 2016 GraphNSF = GraphDB in Domino • Vertices and Edges are stored as Documents • The data container is a NSF • The ElementStore defines the file path to the NSF • An ElementStore can hold different types of Vertices • Usually you create one ElementStore for each Vertex type
  • 13. 8th Sutol Conference, November 2016 Implementation & Data Modeling • Vertices are defined as Interface classes • Fields are defined as properties with Getter and Setter • Methods define how the Node can build Edges to other Vertices • Methods also return all Edges to a certain Vertex • All inside the NSF using ODA
  • 14. 8th Sutol Conference, November 2016 Init the Graph • Define the Element Store(s) • Add Element Store(s) to the Graph Configuration • Define the DFramedTransactionalGraph object with the Graph Configuration • Add Vertex types to Element store(s) • Work with the Graph object
  • 15. 8th Sutol Conference, November 2016 Create an Edge • Parameterize Object 1 • Get Object 2 by a unique key • Call one of the „add“ methods of your Node class • Commit your changes
  • 16. 8th Sutol Conference, November 2016 A strategy? Add some meta data • a most common use case is to add meta data to existing data using Graph data • no need to touch the original data :-) • graph data is highly extensible (like NoSQL is in general)
  • 17. 8th Sutol Conference, November 2016 DEMO TIME! DEMO TIME!
