Event Processing is a computing technique that involves capturing, analyzing, and responding to events in real-time. An event can be anything significant that occurs, such as a user action, a system alert, or data changes. This process allows organizations to react quickly to important occurrences, improving decision-making and operational efficiency. In Event Processing, data is often filtered and aggregated to identify patterns or trends. This can be done using various methods, including Complex Event Processing (CEP), which focuses on detecting complex patterns across multiple events. By leveraging these techniques, businesses can enhance their responsiveness and gain valuable insights from their data.
