5. Why graphs are important?

6. Rise of complex and connected data.
Increase in
volume
New processes, more
transactions, more social
devices, more devices, etc.
Increase in
connectedness
Customers, products,
processes and devices
interact with each other.

7. Relational DBS are not
good at relationships.
● Cannot model data and relationships without
complexity;
● Performance degrades with number and levels
of relationships, and database size;
● Adding new types of data and relationships
requires schema redesign.

8. Graph DBs unlock
connected data.
● Store graphs of billions of nodes and edges;
● Query the graph to find interesting patterns;
● Popularity of graph databases has increased
500% in the last 2 years;
● Recommendation, fraud detection, network
management, cybersecurity, health...
