 # Send data from an OPC UA server to Azure Data Lake Storage Gen 2
 
 In the quickstart, you created a dataflow that sends data from Azure IoT Operations to Event Hubs, and then to Microsoft Fabric via EventStreams.
 
-However, it's also possible to send the data directly to a storage endpoint without using Event Hubs.
+However, it's also possible to send the data directly to a storage endpoint without using Event Hubs. This approach requires creating a Delta Lake schema that represents the data, uploading the schema to Azure IoT Operations, and then creating a dataflow that reads the data from the OPC UA server and writes it to the storage endpoint.
 
 This tutorial builds on the quickstart setup and demonstrates how to bifurcate the data to Azure Data Lake Storage Gen 2. This approach allows you to store the data directly in a scalable and secure data lake, which can be used for further analysis and processing.
