Problems 29–32 are based on the following query:

SELECT CUS_CODE, MAX(LINE_UNITS*LINE_PRICE)
FROM CUSTOMER NATURAL JOIN INVOICE NATURAL JOIN LINE
WHERE CUS_AREACODE = '615'
GROUP BY CUS_CODE;

Assuming that you generate 15,000 invoices per month, what recommendation would you give the designer about the use of derived attributes?

Program Plan Intro

Usage of derived attributes:

  • The derived attributes are used to minimize the computations that are established in the execution of queries and join operations.
  • Derived attributes are highly used during the execution of the aggregate queries.

Explanation of Solution

Recommendation that is given to the designer in the usage of derived attributes:

The below are the recommendations that are given to the designer for the usage of derived attributes:

  • The given query utilizes the aggregate function “MAX” in order to compute the customer’s maximum invoice line number.
  • The given table gets increased at the rows rate of 15,000 per month and because of that the query can take significant amount of time in order of executing the rows that gets increases...
