 ## Query changing IoT data
 
-In Azure Digital Twins, you can query your twin graph to answer questions about your environment, using the SQL-style *Azure Digital Twins query language*. One way to query the twins in your graph is by their properties. Querying based on properties can help answer questions about—or identify outliers in—your environment. In a fully connected, data-driven scenario, the properties of your twins will change frequently in response to IoT data from the sensors in your environment. In this quickstart, you'll change the values manually to simulate a changing sensor reading.

-In a fully connected Azure Digital Twins solution, the twins in your graph receive live updates from real IoT devices, and update their properties automatically to stay synchronized with your real-world environment. For simplicity in this quickstart, you'll use Azure Digital Twins Explorer here to manually set the temperature reading of Room0 to 76.

 The intent of this exercise is to demonstrate how you can use the Azure Digital Twins graph to answer questions about your environment, especially as IoT environments continue to change.
 
-In this quickstart, you made the temperature update manually. It's common in Azure Digital Twins to connect digital twins to real IoT devices so that they receive updates automatically, based on telemetry data. In this way, you can build a live graph that always reflects the real state of your environment. You can use queries to get information about what's happening in your environment in real time.

It's common in Azure Digital Twins to connect digital twins to real IoT devices so that they receive updates automatically, based on telemetry data. You can also [connect other data sources](concepts-data-ingress-egress.md#data-ingress), integrating data from different systems and defining your own logic for how twins are updated.

+You can also export Azure Digital Twins data to historical tracking, data analytics, and AI services to enable greater insights and perform environment simulations. Integrating Azure Digital Twins into your IoT solutions can help you more effectively track the past, control the present, and predict the future.
