Explore how graph databases model data as nodes and relationships. See why Neo4j enables fast queries with complex relationships, compared with relational databases.
Create and drop databases in the new 4G browser, starting with the student database, noting the two defaults: Neophilia default and the system database, and use it to run queries.
Fetch a node's relationships in a Neo4j graph using match clauses, returning related nodes with their relationships and types like learning or belongs to.
Learn to add, update, and delete properties on a specific relationship in Neo4j, such as updating marks to 80 and adding progress to 50 percent, while targeting the correct relationship.
This lecture shows how to update a relationship type by creating a new relationship with the desired type, copying properties (for example mark 70), and deleting the old relationship.
Delete a node with its relationships in Neo4j by first removing all related relationships, then the node. Learn to delete nodes with no relationships to clear the database.
Delete all nodes and relationships in a Neo4j graph with a single query using optional match or detach delete.
Learn how to write contains queries in Neo4j to find nodes where a name contains a substring, and use to lower or to upper for case-insensitive matches.
Discover how to obtain unique names from the graph by applying distinct on the name property in a match query and returning the names.
Explore pagination in Neo4j by applying skip and limit to return finalists across pages; set page size, navigate first, second, and third pages with total nodes.
Define relationships with properties in Spring Data Neo4j by creating a relationship properties class for learning with marks and annotating it with @RelationshipProperties and @TargetNode between student and subject.
Define and use neo4j repositories in a spring boot app by creating student, subject, and department repositories that extend neo4j repository and enable them in the main class.
***** Some Reviews From Students *****
This is a very good step-by-step tutorial. I like that it uses Maven, Postman and Intellij IDEA. The instructor explicitly tells you all the steps to set up your environment so you don't waste a lot of time. It is easy to skip over the stuff I already know and get to the material I need. The code is clearly legible on the screen (no squinting required; full screen mode is not necessary). The instructor is easily understood even at 1.5x speed. Once I got into the Spring Boot section I was quickly running a working application and adding to it. This is the best Udemy course I've ever taken.
Good course. It is quite comprehensive and covers good examples.
wanted to learn graph database Neo4j and this course covers what I was looking for.
This course is all about Neo4j which is Graph Database and it is type of NoSQL.
In this course you will learn Neo4j in detail and also you will learn How to use Neo4j with Spring Boot ?
Below are topics that this course covers :-
What is Graph, Node and Property ?
Neo4j Installation
Create & Drop Database
Create, Read, Update and Delete (CRUD) Operations in Neo4j.
Cypher Query Language (CQL)
AND, OR and IN Queries In Neo4j.
Relationship between Nodes
Relationship Properties
Constraints in Neo4j - Unique Constraint, Property Existence Constraint & Node Key Constraint
Neo4j with Spring Boot using Spring Data Neo4j
Create, Read, Update and Delete (CRUD) Operations using Spring Data Neo4j
AND, OR and IN Queries using Spring Data Neo4j
Optional Match and Detach Delete
May be you are thinking why to learn Neo4j ?
The answer is when you have complex relations in your SQL database then if you try with query which has lot of JOINS in it then it will slow down the performance where as Neo4j is faster as compared to SQL databases.
Neo4j is being used by companies like Airbus, Walmart, eBay, Adobe etc.
By end of the course you will be able to manage data in Neo4j Graph Database along with your Spring Boot Application. You will be able to execute CQLs to perform different operations in Neo4j.
This course covers Neo4j with Spring Boot because Spring Framework is widely used among Java Developers.
