--defining variables
W_CK NUMBER := 0;
W_SUBT NUMBER := 0;
W_TAX NUMBER := 0;
BEGIN
--Authentication process of the invoice
SELECT COUNT(*) INTO W_CK FROM INVOICE WHERE INV_NUMBER := W_IN;
--Transaction confirmation
IF W_CK = 1 THEN
SELECT SUM(LINE_TOTAL) INTO W_SUBT FROM LINE
WHERE
--checking the invoice for the desired invoice number
LINE.INV_NUMBER = W_IN;
W_TAX :=W_SUBT * 0.08;
--updating the invoice
UPDATE INVOICE
--setting the new values
SET INV_SUBTOTAL = W_SUBT,
INV_TAX = W_TAX,
INV_TOTAL =W_SUBT + W_TAX
WHERE INV_NUMBER = W_IN;
--ending the if statement
END IF;
--ending the procedure
END;
Answer:
By definition, <u>multiprocessing</u> refers to the processing of multiple processes at the same time by multiple CPUs.
By definition, <u>multiprogramming</u> keeps programs in main memory at the same time and execute them concurrently utilizing a single CPU doing a context switch.
The first difference is that multiprocessing uses multiple CPUs and multiprogramming to utilize context switch to do concurrency in one CPU. Another difference is that multiprocessing is more expensive but more efficient than multiprogramming due that it allows parallel processing.
