Data feeds are streams of data that provide real-time or regularly updated information from various sources. They are commonly used in industries like finance, e-commerce, and news to deliver content such as stock prices, product listings, or breaking news. Data feeds can be structured, like XML or JSON formats, making it easier for applications to process and display the information. These feeds can be accessed through APIs (Application Programming Interfaces) or direct connections, allowing businesses to integrate external data into their systems. By utilizing data feeds, organizations can enhance their decision-making processes and improve user experiences by providing timely and relevant information.
