Data Feeds
Data feeds are continuous streams or periodic updates of structured data delivered from a source to a destination, often in real-time or near-real-time. They are commonly used to distribute information such as financial market data, news articles, sensor readings, or social media updates, typically in formats like JSON, XML, CSV, or via APIs. This concept enables systems to stay synchronized with dynamic data sources, supporting applications like analytics, monitoring, and automated decision-making.
Developers should learn about data feeds when building applications that require up-to-date information from external sources, such as stock trading platforms, IoT dashboards, or news aggregators. They are essential for scenarios where latency is critical, like real-time analytics or live updates in web applications, as they provide efficient mechanisms for data ingestion and processing without manual intervention.
