Neo4j is an open source graph database that uses nodes, relationships, and properties to store and query data. It supports ACID transactions and is high performance. Cypher is Neo4j's query language that allows matching patterns of nodes and relationships. A graph database model uses nodes connected by relationships, unlike a relational database that uses tables and rows.

4. Graph Database
A graph database is not
about charts, diagrams or
vector artwork, it is related
with storing data that is
structured as a graph.
remember linked lists,
trees?

5. What is Graph Database?
● NoSQL Database
● Collection of nodes, edges and properties to represent
and store data.
● Provides index-free adjacency
● Properties expressed as key/value pairs
● High Performance
● Complex Relationships

6. What is Neo4j?
● Open Source
● NoSQL Graph Database
● ACID transaction compliance
● Runtime Failover
● Cluster support
● Compact storage
● Memory caching for graph
● Active Community

7. Cypher - Query Language
● Cypher is Neo4j’s graph query language.
● Match patterns of nodes and relationships in the graph
Example:
MATCH (actor:Person)-[:ACTED_IN]->(movie:Movie)
WHERE movie.title =~ "T.*"
RETURN movie.title as title, collect(actor.name) as cast
ORDER BY title ASC LIMIT 10;

8. From SQL To Cypher
SQL Cypher
SELECT p.*
FROM products as p;
MATCH (p:Product)
RETURN p;
SELECT p.ProductName, p.UnitPrice
FROM products as p
ORDER BY p.UnitPrice DESC
LIMIT 10;
MATCH (p:Product)
RETURN p.productName, p.unitPrice
ORDER BY p.unitPrice DESC
LIMIT 10;
SELECT p.ProductName, p.UnitPrice
FROM products as p
WHERE p.ProductName IN
('Chocolate',Coffee);
MATCH (p:Product)
WHERE p.productName IN
['Chocolate',Coffee]
RETURN p.productName, p.unitPrice;

9. Graph DB Model
● Nodes
● Labels
● Relationships
