Data by itself has little value, it’s the
relationship
between data that gives it
incredible value

Found!
This lookup took 5 steps.
With millions of indexed
records, the tree depth
could be 1000’s of levels!

Joins are executed every time
you cross relationships
Querying million of records
joining 3-4 tables could
generate billions of
combinations

This is why the database
query performance
suffers as the database
increases in size
O(Log N)

PERFORMANCE
DATABASE SIZE
RDBMS performance on traversal

Solution: Graph Database!

“A graph database is any
storage system
that provides
index-free adjacency”
- Marko Rodriguez
(author of TinkerPop Blueprints)

N-M relationships

Congrats! This is your diploma in
«Graph Theory»

How does a true*
Graph Database
manage relationships?
*a “Graph” layer on top of a DBMS doesn’t qualify as a true GraphDB

A Graph Database creates the
relationship just once
(when the edge is created)
VS
RDBMS computes the
relationship every time
you query a database

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

No costs to traverse relationships:
• Recommendation engines
• Social Applications
• Spatial Apps
• Master Data Management
• Information Clustering

So the Graph Model
Is the only solution to efficiently
manage relationships
But what about data complexity?
And data consistency?
And scaling?

- No standard between NoSQL

- Multiple vendors = multiple skills
- ETL + synchronization code
