<u>Some recommend way to prove the authenticity of an email:</u>
- The coworker as truthful to the company or organization he or she has to check where the same mail is sent long back to the same sender.
- If search on emails sent item if he sends it will be well and good. Some time backup the mail will be help to proven authenticity of an email.
- Sometimes once mail is downloaded into ms-outlook or lotus domino some time mail persists in the mail server.
- He or she can coordinate with the mail server administrator to possible get a log file of sending mail and he can proceed as a record to management.

Explanation:
Assuming Cust_code is unique for every customer.
Query :
SELECT * FROM CUSTOMER WHERE CUST_STATE= "AL" GROUP BY CUST_CODE HAVING LARGEST INVOICE = MAX(LARGEST INVOICE) OR (LARGEST INVOICE =0 and INV_DATE IS NULL);
Answer:
Hi, for this exercise we have two laws to bear in mind:
Morgan's laws
NOT(А).NOT(В) = NOT(A) + NOT (B)
NOT(A) + NOT (B) = NOT(А).NOT(В)
And the table of the Nand
INPUT OUTPUT
A B A NAND B
0 0 1
0 1 1
1 0 1
1 1 0
Let's start!
a.
Input OUTPUT
A A A NAND A
1 1 0
0 0 1
b.
Input OUTPUT
A B (A NAND B ) NAND (A NAND B )
0 0 0
0 1 0
1 0 0
1 1 1
C.
Input OUTPUT
A B (A NAND A ) NAND (B NAND B )
0 0 0
0 1 1
1 0 1
1 1 1
Explanation:
In the first one, we only need one input in this case A and comparing with the truth table we have the not gate
In the second case, we have to negate the AND an as we know how to build a not, we only have to make a nand in the two inputs (A, B) and the make another nand with that output.
In the third case we have that the OR is A + B and we know in base of the morgan's law that:
A + B = NOT(NOT(А).NOT(В))
So, we have to negate the two inputs and after make nand with the two inputs negated.
I hope it's help you.
