A crucial part of the book is mastering DTDL. This is the language used to describe the interfaces of your digital twins, including properties, telemetry, commands, and relationships. C. Hands-On Implementation
Understanding Digital Twin Definition Language (DTDL).
With a live graph, users can execute rich spatial queries using the ADT query language (which is highly reminiscent of SQL). For example, an operator can run a query to find "all rooms on Floor 3 where the temperature exceeds 75°F and the occupancy sensor is active." Key Takeaways from "Hands-On Azure Digital Twins"
