Populating your graph in Amazon Neptune from a relational database using AWS Database Migration Service (DMS) – Part 4: Putting it all together

In this four-part series, we cover how to translate a relational data model to a graph data model using a small dataset containing airports and the air routes that connect them. Part one discussed the source data model and the motivation for moving to a graph model. Part two explored mapping our relational data model to a labeled property graph model. Part three covered the Resource Description Framework (RDF) data model. In this final post, we show how to use AWS DMS to copy data from our relational database to Neptune for both graph data models. You may wish to refer to the first three posts to review the source and target data models.
