Dataflow refers to the movement of data between different components in a system, often visualized as a series of steps or processes. It describes how data is collected, processed, and transferred from one point to another, ensuring that information is efficiently managed and utilized. In computing, Dataflow can also refer to a programming model where the execution of operations is determined by the availability of data. This model allows for parallel processing, making it suitable for applications that require high performance and scalability, such as big data analytics and stream processing.
