NoSQL: Neo4j and Cypher (Part: 2-Intermediate)

Lets take a look at the OPTIONAL MATCH Cypher command. I demonstrate its use to help use DELETE the old database from Part: 1 of this course.

We take a look at the 'Learning Market Place' case study, which we will be using in the course as our example Neo4j database. I walk through the structure and the Cypher code and then show how to run the script to install the database.

The first tutorial in several that looks at 'Patterns & Paths' and what they are. Understanding this is key to having a great experience using Graph Databases like Neo4j.

Continue our in-depth learning about 'Patterns & Paths' and how to get the most from them. Here we look at Node Labels to help us refine out graph queries.

Continue our in-depth learning about 'Patterns & Paths' and how to get the most from them. Here we look at patterns involving 3 Nodes.

Final part of our in-depth learning about 'Patterns & Paths' and how to get the most from them. Here we look at patterns involving 3 Nodes.

The WITH clause enables us to break up our Cypher queries into smaller easy to handle parts. This tutorial shows how.

We will look at the Count function and how to get the most from it.

We look at how to use the RETURN clause to aggregate data using MIN, MAX and SUM functions.

If statistical functions provided by Cypher are not enough for your needs, you can collect all the values in an array so that you can easily process them with your preferred algorithm.

This Tutorial covers the basics of what a Variable length paths are.

In this Tutorial we look at variable length paths up to 3 hops away.

In this Tutorial we look at variable length paths using Hop ranges and then how to determine the shortest path(s).

In this Tutorial we look at how to do Text searching in Neo4j and Cypher.

The IN predicate allows us to specify more values for an expression, this tutorial shows how.

Collection predicates are functions with a predicate argument that return a Boolean value.
