How Does it Differ from a Measure in a Cube?

While a measure group is a logical collection of related measures, a measure in a cube represents a single numerical value that can be aggregated, such as sales revenue or quantity sold. Measures are the actual data points that are being analyzed in a cube, whereas measure groups provide a higher level of abstraction by grouping related measures together for easier management and organization.
