2. What are we going to do?
• Why graphs?
• What do we use graphs for?
• Graph Theory explained
• Extending Practical Graph Use: The Property Graph Model Revolution
• Use Case 1: Measuring risk in corporate lending
• Use Case 2: Understanding the exposure to commodities or industries
• Use Case 3: Predicting behavior of customers

3. Why graphs?

4. The world is a graph – everything is connected
• people, places, events
• companies, markets
• countries, history, politics
• sciences, art, teaching
• technology, networks, machines,
applications, users
• software, code, dependencies,
architecture, deployments
• criminals, fraudsters and their behavior

5. What Industry Analysts are Communicating
about Graph Database
• “Graph analysis is possibly the single most effective competitive
differentiator for organizations pursuing data-driven operations and
decisions after the design of data capture.”
• “Graph analysis is the true killer app for Big Data.”
• “…(Software) vendors are investing in Graph Databases.”
• “Graph repositories help MDM better connect conceptual master data
models with logical models…that RDBMS repositories often constrain.”

15. Graph Theory

16. The Koningsberg Bridge Problem
The basic idea of graphs were introduced in 18th
century by the great Swiss mathematician Leonhard
Euler.

17. Breaking down the “bridge problem”
• The Euler cycle (or tour) problem: Is it possible to traverse each of
the edges of a graph exactly once, starting and ending at the same
vertex?
• The Hamiltonian cycle problem: Is it possible to traverse each of the
vertices of a graph exactly once, starting and ending at the same
vertex?

18. Essential Graph Types

19. What’s all the fuss?
• Vertex = a point where two lines meet
• Edge = lines that join to form vertices

20. Neo4j Fundamentals

21. What if?
• A vertex could represent something more concrete?
• A customer
• A business
• An asset
• What if edges could provide more context
• Cash flow
• A Transaction (withdraw, deposit)
• A meaningful interaction (borrows from, supplies to)

22. What if I could view all of my business data as a graph?

23. Enter the property graph model

30. Commerical Lending
Risk Management

31. 31
• Character - The Borrower’s history of how they pay their bills;
• Capacity - The quantitative measure of whether the Borrower has
sufficient income to pay its debts;
• Capital - Also known as equity. Generally, the higher the equity
contribution, the lower the risk to the Bank;
• Collateral - An alternative source of repayment if cash flow cannot
be relied upon to pay the debt; and
• Conditions - Also known as loan structure. This refers to both the
return built into the investment (the interest rate being charged) as
well as the conditions placed on the accommodation to ensure the
Bank is repaid (hopefully in full!).
Commercial Lending and Risk

We need a better understanding of the business “community” to understand
how business relationships are affecting loan risk.
Problem Statement:

33. 33
”Knowing your customers and the markets in which they invest are two of the
simplest and most basic tools of understanding risk. Living, working and playing
in the same community as your Borrower is a surefire way to know their
business environment.”

We need more ways to determine our credit exposure to commodities and oil
in particular
Problem Statement:

43. 43
Commodities Impact Industries You Might Not Expect
• Do you know how all of your customers are connected, directly or indirectly to the
oil industry?
• How will a precipitous drop in oil prices affect the businesses that you invest in or
provide credit to?

Predicting Customer Behavior

51. 51
“Underwriting involves assuming a risk on behalf of an investor selling securities in the
stock market. The company wants an assurance that money is raised for the stock
issued even when some shares have not been sold. Investment bankers place their
capital risk by buying all the securities from the company at a discounted price. Bankers
then mark up the securities to market retail price and sell them to the investing public.
If the sale of securities does not reach the target capital requirement, bankers are
forced to borrow from commercial banks or sell the shares at a loss. Alternatively, they
also invite other investment banks to take part in the underwriting process to share the
risk of loss in form of an underwriting syndicate.”
Joseph Petrick,

Investment Banking / Underwriting and Selling

We need to be better prepared to support our customers trades so that we
are less likely to suffer a loss. To do that, we need to better predict when and
what our customers are likely to want to buy or sell.
