Hands-On Azure Digital Twins

By: Alexander Meijers

Overview of this book

In today’s world, clients are using more and more IoT sensors to monitor their business processes and assets. Think about collecting information such as pressure in an engine, the temperature, or a light switch being turned on or off in a room. The data collected can be used to create smart solutions for predicting future trends, creating simulations, and drawing insights using visualizations. This makes it beneficial for organizations to make digital twins, which are digital replicas of the real environment, to support these smart solutions. This book will help you understand the concept of digital twins and how it can be implemented using an Azure service called Azure Digital Twins. Starting with the requirements and installation of the Azure Digital Twins service, the book will explain the definition language used for modeling digital twins. From there, you'll go through each step of building digital twins using Azure Digital Twins and learn about the different SDKs and APIs and how to use them with several Azure services. Finally, you'll learn how digital twins can be used in practice with the help of several real-world scenarios. By the end of this book, you'll be confident in building and designing digital twins and integrating them with various Azure services.

Getting relationships

It is very handy to get relationships as we can get a related digital twin based on a relationship. An example of this is getting all the floors for a certain building. Relationships can be retrieved in two ways:

  • Getting a single relationship: Get a relationship based on the source digital twin and the target digital twin.
  • Getting a list of relationships: Get a list of relationships from a source digital twin.

Let's explain these in more detail. We will start by getting a single relationship.

Getting a single relationship

Let's start by creating a method that retrieves a relationship based on the source digital twin and the target digital twin. This allows us, for example, to access the properties specified for that relationship.

Create a new method for getting a relationship. Add the following code to the DigitalTwinsManager class:

public BasicRelationship GetRelationship(string twinSourceId, string twinDestinationId)...
