A graph?

Yes, a graph...

�15

๏you know the common data structures

•linked lists, trees, object "graphs"

๏a graph is the general purpose data structure

•suitable for any connected data

๏well-understood patterns and algorithms

•studied since Leonard Euler's 7 Bridges (1736)

•Codd's Relational Model (1970)

•not a new idea, just an idea who's time is now

�16

How can you use this? With a Graph Database

A graph database...

�17

๏optimized for the connections between records

๏really, really fast at querying across records

๏a database: transactional with the usual operations

๏“A relational database may tell you the average age of everyone here,

but a graph database will tell you who is most likely to buy you a beer later.”

What’s love got to do with it?
