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.

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. In this post, we explore mapping our relational data model to a labeled property graph model. You may wish to refer to part one of the series to review the source relational data model. Part three covers the Resource Description Framework (RDF) data 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.

We discuss this for the labeled property graph in part two and for the Resource Description Framework (RDF) data model in part three.

In this post, I describe firstly how you can create a new Amazon Neptune cluster on the console. then by using a NAT Gateway configure your Amazon VPC network to enable SPARQL 1.1 Federated Query.

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, […]

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.

This is a guest post from Shahria Hossain, Software Engineer, and Mikael Graindorge, Sales Operations Leader at Thermo Fisher Scientific. The continuous expansion of data volume is a growing challenge for businesses to produce strategic solutions for their customers. Thanks to innovative approaches, these challenges have become simpler to solve with the rise of new […]

Neptune is a fully managed graph database service that makes it easy to build and run applications using highly connected datasets. Neptune is a purpose-built, high-performance graph database engine optimized for storing billions of relationships and querying the graph with milliseconds latency. Neptune supports both the Property Graph and the Resource Description Framework (RDF) standard.

[Updated August 2021] The Gremlin Client for Amazon Neptune is now available from Maven Central. Some APIs have changed since this article was published. Please review the demo code in the GitHub repository for the latest examples of how to use the APIs. Amazon Neptune is a fast, reliable, fully managed graph database service that makes it easy to build and […]

“I’m hungry. Where should I go to eat?” It’s one of the most common questions we ask ourselves every day, and when you’re going out to spend money somewhere, you don’t want to simply pick a random place and try it—you want some sort of assurance that the restaurant you choose matches what you’re looking […]
