Description

With increase in complexity of data relationships, graph databases are quickly becoming the de-facto standard for organizations who manage large volumes of connected data. Neo4j is a graph database that allows traversing huge amounts of data with ease. It is the world's leading graph database management system which is designed for optimizing fast management, storage, and traversal of nodes and relationships.

Starting with a brief introduction to graph theory, this course will show you the advantages of using graph databases along with data modelling techniques for graph databases. You will gain practical hands-on experience with commonly used and lesser known features for updating graph store with Neo4j's Cypher query language. You will learn to use it for artificial intelligence, fraud detection, graph-based search, network ops & security, and many other use cases.

Furthermore, you will learn the important graph algorithms which are used in Neo4j’s graph analytics platform wherein you will explore various high-performance graph algorithms that help reveal hidden patterns and structures in your connected data. You will also gain skills to use the algorithms efficiently to understand, model, and predict complicated dynamics.

By the end of this course, you will be confident using graph analytics with Neo4j to effectively handle large volume of connected data and to use its quick insights to wield powerful results.
