Neo4J Data Access

In the course Neo4J Data Access from SpiralTrain the participants learn to store and access data in the Graph database management system Neo4J.

Intro Graph Databases

The course starts with an explanation of the basic concepts of Graph databases in which data is modelled in the form of a graph. The nodes of a graph represent the entities and the relationships between the entities are represented by the associations between the nodes.

Property Graph Model

Next the Property Graph Model in Neo4J and the possible relationship types are discussed. Nodes and relations store data in key-value pairs called properties. Node Labels, Graph Global Operations and In Graph Indexes are also discussed.

Cypher Query Language

Extensive attention is also paid to the Cypher Query Language that is used in Neo4J for data access. Path finding queries, the use of parameters and complex queries are discussed and the Neo4J Data types as well.

Query Clausules and Functions

The various Cypher Query clauses such as CREATE, MERGE and SET are treated and the functions available in the Cypher Query language are also part of the course program.

Neo4J Shell Tools

The course concludes with a discussion of the use of Neo4J in Java and Spring applications, importing data from CSV files, batch inserts and the Neo4J Shell Tools.

Audience Course Neo4J Data Access

The course Neo4J Data Access is intended for software developers who want to use the Graph Database Neo4J to access, query and modify data.

Prerequisites Course Neo4J Data Access

Experience with software development in a language like Java, C#, JavaScript or Python is required and knowledge of JSON is recommended.

Realization Training Neo4J Data Access

The course has a hands-on character. The theory is treated on the basis of presentation slides and is interchanged with practical exercises. Course times are from 9.30 up and to 16.30.

Certification Neo4J Data Access

After successful completion of the course the participants receive an official certificate Neo4J Data Access.
