Quizplus · Accepted Answer

The activity ratio is the number of accessed records divided by the number of records in the file. This ratio determines the efficiency of file processing and the resources required. A high activity ratio indicates that a large proportion of the file is being accessed, which may require more processing power and storage. A low activity ratio suggests that the file may be optimized by reducing its size or restructuring the data.
