Detailed technical explanation
How to think about this question
Power BI leverages DirectQuery and live connections to push data from sources like Azure SQL Database or Dynamics 365 in near real-time, using the XMLA endpoint for tabular models. Its real-time datasets can be configured with streaming dataflows that update visuals every second, making it suitable for scenarios like monitoring live sales transactions or IoT sensor feeds. This contrasts with scheduled refresh, which introduces latency.
