Description: This course explores a variety of Cypher queries that go beyond simple reads and writes. The course also involves identifying complex patterns and combinations of data in nodes and relationships.
Begin with a deep dive into querying for patterns in relationships. Move on to the operation of finding the shortest paths between two nodes in a graph structure. Next, explore queries based on the properties of nodes or relationships, where you will look for elements matching a single criterion as well as multiple criteria defined using logical operations. Following that, explore some of the fundamental aggregation operations which can be performed on data using the Cypher language on both text and numeric data. Finally, discover how to order query results and limit their size using the LIMIT and SKIP clauses.
Upon completion, you'll know how to apply graph-specific and generic database features to analyze a Neo4j database using the Cypher language.

Description: This course introduces you to the breadth of operations which can be performed using the Cypher query language to add, modify, and delete nodes and relationships.
Kick things off with queries that create multiple nodes and relationships in a single operation. Move on to MATCH queries where you search for relationships based on a variety of different patterns. Then, delve into the OPTIONAL MATCH clause to search based on partial pattern matches. Next, discover how to update operations where node properties are created, changed, or removed. Explore the MERGE clause in the Cypher language. This clause is similar to the CREATE clause but has a few notable differences that make it the better choice in many scenarios. Finally, learn how nodes and relationships in Neo4j can be removed and some of the rules around such operations.
After completing this course you'll be able to add, modify, and delete nodes and relationships in a Neo4j database using the Cypher query language.

Description: This first course in the path delves into the basics of the Cypher query language. You will learn about the creation of nodes, relationships between nodes, and how to search for simple patterns among them.
Begin with a simple query with a CREATE clause in order to create a node. Build upon your query at each step, starting with an empty node, then creating nodes with properties and nodes containing one or more labels. You then move on to setting relationships between nodes. Define relationships between existing nodes in the database, and build nodes containing their own properties. All the while, gaining familiarity with the syntax of CREATE queries in the Cypher query language, how directions are set when defining relationships, and the rules and conventions around names for node labels and relationships.
After completion of this course you'll know how to create nodes and relationships between nodes in a Neo4j database using the Cypher query language.
