► Graphs have all possible logical relationships precomputed, much, much faster than SQL
► Graphs are fast and easy understand, develop and use
► Graphs integrate well with applications and data sources, great for real-time digital workloads
► Graphs surface, unify and mobilize data held in silos and data lakes

Key Conversations

13. Talk to the business, pick a graphy problem
What is a “Graphy” problem?
• Requires many entities (eg many SQL tables, 360° views)
• Involves recursion (eg. SQL self joins)
• Has complex, potentially colliding, hierarchies (eg SQL 1 to many, many-to-many)
• Based on informatics of the relationships themselves (eg collaborative filtering shared
relationship counts, shortest path segment summations for wayfinding, cost/time
minimization for supply chain, money flows for finance)
• Requires mapping, direct or indirect across data sources (eg data lake unification)
• Demands fast query results (eg digital applications, search)
• Most importantly, go talk to the business – what are the analytics you’d like to have or
customer experiences you’d like to light up – but can’t because of our current data
limitations?
• What’s the most critical data that you’d like to see connected?
• What would be an example demo that you’d find compelling (report/analysis/experience)
13
Production BuildCloud PilotLocalhost POCGraphy Problem

14. Get comfortable with Neo4j – don’t need to become an expert
• Get hands on – be fearless! Neo4j is the easiest graph database to
learn.
• Install Neo4j, Apoc procedures, set the following in Manage/Settings
#Apoc Plugin Configurations
apoc.import.file.enabled=true
apoc.export.file.enabled=true
dbms.security.procedures.unrestricted=*.*
• Go through the Cypher lessons, and learn basics graph modeling and to
load csv
LOAD CSV WITH HEADERS FROM "file:///movies.csv"
AS row
CALL apoc.load.csv(url,{}) YIELD map
• Any reasonably sized laptop should be able to handle a graph with
several million nodes and relationships You will quickly see some of the
significant benefits of connected data.
• For extra credit you can go onto github/neo4j-examples and download
starter applications for your favorite languages.
14
Production BuildCloud PilotLocalhost POCGraphy Problem

15. Design and build your POC Graph
• Start small and simple, limit yourself to 3-4 data sources, shallow extracts.
Snapshot SQL top queries for a pool of linked transactions
• Use common sense, business-friendly naming for your node labels and relationship
types. You’ll iterate this model using input from the business, and the model
should be clear and readable
• Don’t be afraid of recursion
(Employee)-[:REPORTS_TO]->(Employee) who is the boss?
• Don’t get too hung up on whether something should be a node label, property, or
relationship. Just keep in mind that node labels define set members, and that it’s
faster to search along relationships (traversal) than properties (full graph scan)
• You can use call db.schema() to see the graph schema, and we often use
http://apcjones.com/arrows/# to build illustrative schemas for conversations with
business stakeholders
• Test your graph design by writing some example queries, do this with your business
stakeholder
• Does this look right to you – is this how you would whiteboard this process? Am I
missing any key entities or relationships?

sourcing complexity of
products and services
• Enables more insightful
indirect spend analytics for
products and services
• Reconciles line-item detail to
top parent company, across
intermediate entities

detection, tracking &
traceability
• Integrates with data lake,
reporting platforms and
transactional applications

Master Data
Management
Graph Schema
• Accurately captures data
lineage for core identity
components
• Provides ”Golden Record”
from multi-source
probabilistic authority
scores
• Relates contacts, customers,
orders and products without
loss of fidelity
• Enables detailed whitespace
analysis and next best sales
action
• Integrates with data lake
and CRM applications

19. Example Polyglot Discovery Graph Schema
Searchable Pointers to
Unstructured blobs
Text & Metrics from
Semi-Structured

Data Discovery
Graph Schema
• Connects structured, semi-
structured and unstructured
data across polyglot storage
• Accurately handles complex
data and documents
hierarchies
• Enables full text search in
graph or in document store,
directly and via NLP
• Provides source document
access through blob URLs
• Integrates with data lake,
reporting platforms and
transactional applications

20. Design and build your POC Graph 20
Production BuildCloud PilotLocalhost POCGraphy Problem
• Breakthrough queries
• Graph algorithms
• Data unification & mobilization
• Use-case specific (Customer 360, Supply Chain, Fraud, Reco)
• Make a localhost graph->app stack so you understand how
parameterized Cypher & Bolt drivers work
• Use any of the neo4j-examples to jumpstart
• If you don’t want to spend time creating a REST API, check out
GraphQL and the GRAND stack (https://github.com/grand-
stack/grand-stack-starter)
• Focus on the business value of the new graph enabled analytics –
We can now know this to make better decisions
We can now do this for our customers

21. Pick and build your demo application for your snapshot graph 21
Production BuildCloud PilotLocalhost POCGraphy Problem
• Pick a cloud or on-prem
• Use Marketplace images if possible
• Start with a single instance VM for Neo4j, (~ RAM 50% of SQL size)
• Attach external drives so you can scale the server
• Determine your stack architecture
• Understand your data processing requirements
• Install Python – very good for performing batch operations, pip neo4j-driver
• Leverage Neo4j’s high speed loader
• Determine what cleansing needs to occur
• If you need help reach out to SI partner or Neo4j services

22. Pick and build your demo application for your snapshot graph 22
• MVP data domains
• Graph database, app-informed
• Simplest data service
• MVP app experience
• Add new experiences, same data
• Add new data domains
Nodejs, .Net, Python, React, Swift, Tableau, etc.
