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 social media to deliver content such as stock prices, product listings, or news updates. Data feeds can be structured, like XML or JSON formats, or unstructured, depending on the type of information being shared. These feeds allow businesses and applications to access and integrate data efficiently, enabling better decision-making and improved user experiences. By utilizing data feeds, organizations can automate processes, keep their systems updated, and respond quickly to changes in the market or user behavior.
