Use Azure Stream Analytics, an event-processing engine, to examine high volumes of streaming data. Incoming data can be from devices, sensors, websites, social media feeds, applications, or other sources. Stream Analytics also supports extracting information from data streams and identifying patterns and relationships.
SQL Database Edge does all that and also includes the capabilities of SQL Database for storage, processing, and analytics of data at the edge. Use SQL Database Edge in a disconnected, semi-connected, or rarely connected deployment where local storage and analytics are important.
