Session: Graph Databases

Big Data Workshop, April 23, 2010
Graph Databases – 3A

Title: Graph Databases
Convener: Johannes Ernst
Notes-taker: Dylan Clendenis

Notes:

Different representations:
Relational

  • tables
  • rows, columns
  • SQL

Heirarchical

  • parent/child

Graph

  • nodes, edges, directions

Graph Primitives

  • basic manipulation: set/get properties, “bless/unbless” relationship
between nodes
  • traversal: given a node, get set of neighbor nodes, subset by type
or property value

It is important to make the conceptual shift from “querying” to traversing
