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.

Populating your graph in Amazon Neptune from a relational database using AWS Database Migration Service (DMS) – Part 3: Designing the RDF Model

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 covered designing the property graph model. In this post, we explore mapping our relational data model to a Resource Description Framework (RDF) model. You may wish to refer to parts one and two of the series to review the model. In part four, we show how to use AWS DMS to copy data from a relational database to Neptune for both graph data models.

Populating your graph in Amazon Neptune from a relational database using AWS Database Migration Service (DMS) – Part 1: Setting the stage

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 discusses the source data model and the motivation for moving to a graph model. We discuss this for the labeled property graph in part two and for the Resource Description Framework (RDF) data model in part three. In part four, we show how to use AWS DMS to copy data from a relational database to Neptune for both graph data models.

Write a cascading delete in SPARQL

Customers often manage tree structures in their graph applications. Typical examples include categories of topics in a knowledge graph, relationships between people in an identity graph, or transaction networks in a financial application. Often, the structures are actually forests (collections of trees) with shared subtrees. In these applications, you frequently need to traverse a tree, […]

Graph your AWS resources with Amazon Neptune

In this post, we walk through an example we released for Neptune with integration with Altimeter. Altimeter is an open-source project (MIT License) from Tableau Software, LLC that scans AWS resources and links these resources into a graph. You can store, query, and visualize the data in Neptune. You can query the graph to examine the AWS resources and their relationships in an account. For example, you can query for resources or pathways that expose a cluster with a public IP address to check for security and compliance.
