Graph data structures are quite intuitive and highly flexible. They’re used to conduct queries in databases and interconnect entities in data networks. Elixir, with its power of concurrency and data- and graph-aware packages, is the perfect language to explore graph data structures.

In this course, you’ll learn basic graph data structures and build a simple graph model. Next, you’ll build a testbed umbrella application to compare native graph structures with external databases. You’ll also learn to query graph database systems using Elixir packages Cypher and Gremlin with property graphs and SPARQL with RDF graphs. Next, you’ll learn how to transform data from one graph model to another. Finally, you’ll learn why property graphs are especially good at graph traversal problems while RDF graphs shine at integrating different semantic models and can scale up to web proportions.

After this course, you’ll be able to work with distributed graph datasets and manage data at scale.
