Neo4j is leading the world’s fastest
growing database segment:
Graph Databases
RDBMS
Hadoop
DB-Engines is an independent site using objective data from Google Trends, LinkedIn, StackOverflow, etc.
Growth rate over time

Neo4j is relied on by:
…and over 150 others
“We found Neo4j to be literally thousands of times faster than our prior MySQL solution, with queries that require 10 to 100 times less code. Today, Neo4j provides eBay with functionality that was previously impossible.”

Identifying Challenges
Business Challenges
• Competitor pressure• Real-time response
time• Need to do 10x more
with 10x less• Growth pushing old
systems against the wall
Architecture Challenges
• The requirements will change later
• Iterative development clashes with schema
• Real-time reads with simultaneous writes
Development Challenges
• Poor JOIN performance• Building a flexible &
extendable data model• Transactional operation• Code becoming hard to
evolve

Neo4j Customer Journey
Better Development
“Yeah… so we need to store and query data relationships as a graph. We will use a tabular database because it’s what we always use.”
You what, mate?
Better DevelopmentDon’t reinvent the wheel! It’s costly and will set you back.
Let Neo4j do the heavy lifting for you. We have spent over a decade with 200+ customers building the world’s leading graph database.
Keep your team focused on building your product and business, not a complex database solution.
Better DevelopmentSay goodbye to denormalized query views
Query live data as it’s being updated, all in real time with Cypher or Java APIs
Scale your infrastructure proportionally and reasonably
Orders-of-magnitude improvement on modest hardware

Selected Case Study
AirbusDesign Dependency Analysis
Airbus
• 63’000 employees
• €60 Billion revenue in 2014
• 437 operators globally:
Airbus – The Challenge
• Aircraft design process generates large amounts of design assets
• A given part of the model may be referenced in many places
• It becomes increasingly costly to analyze the impact of a change
Airbus – Evaluating Neo4j
• By mapping the dependencies among the assets, impact can be understood up-front immediately
• 10x required performance with 100 million items and 1B+ links
• Neo4j evaluated in short amount of time with expert assistance
Airbus – Value of Solution• Shifting a slow process to become
real-time, increasing productivity while reducing frustration and mistakes
• Engineers can immediately validate changes being made against the relevant dependencies
• Focus shifted from “how do we build this” to “what should we build next?”
Airbus – Value of Solution
• Leverage data relationships between design assets to work smarter
• Allow engineers to spend more time on valuable work by making impact and dependency analysis very simple
