Based on the ER model shown in Figure P11.7 and on the query shown after the figure.

Figure P11.7:

Given the following query

SELECT        P_CODE, P_PRICE 

FROM          PRODUCT

WHERE        P_PRICE >= (SELECT AVG(P_PRICE) FROM PRODUCT);

Assuming that there are no table statistics, what type of optimization will the DBMS use?
