Consider SELECT statements listed below. SELECT L_PARTKEY, L_TAX, COUNT(*) FROM LINEITEM GROUP BY L PARTKEY, L_TAX; SELECT O TOTALPRICE, COUNT(*) FROM ORDERS GROUP BY O TOTALPRICE; SELECT L_TAX, L_QUANTITY, COUNT(*) FROM LINEITEM GROUP BY L TAX, L_QUANTITY; SELECT O CLERK, O_TOTALPRICE, COUNT(*) FROM ORDERS GROUP BY O CLERK, O_TOTALPRICE; Write SQL statements that create the smallest number of materialized views that can be automatically used to speed up the processing of SELECT statements given above.
