Explanation

A continuous data feed (also called a live or real-time data feed) streams data constantly and automatically updates the dashboard as new transactions occur. Since the dashboard must reflect current sales during an active promotion, real-time ingestion is required. A static data feed delivers a fixed snapshot of data at a single point in time and would quickly become stale. Web scraping extracts data from websites and is not a structured acquisition method for internal sales systems. A web interface is a UI element, not a data acquisition mechanism.
