Answer:
Grace Hopper.
Explanation:
Grace Hopper was a US Naval Rear Admiral and an American computer scientist who was born on the 9th of December, 1906 in New York city, United States of America. She worked on the first commercial computer known as universal automatic computer (UNIVAC), after the second World War II.
In 1953 at the Remington Rand, Grace Hopper invented the first high-level programming language for UNIVAC 1 by using words and expressions.
Hence, Grace Hopper was the Navy Admiral who invented a high-level programming language FLOW-MATIC in 1953.
Additionally, FLOW-MATIC paved the way for the development of common business-oriented language (COBOL).
Answer:
The expression is :
π[cd) + π(g,h) ],[π(e,f)+π(a,b)])
We will use foreign key and primary key
The SQL statement that would create the GET_CREDIT_LIMIT procedure to obtain the full name and credit limit of the customer is:
GET_CREDIT_LIMIT
SELECT CUST_ID 125
FROM FIRST_NAME, LAST_NAME, CREDIT_LIMIT
WHERE LAST_NAME ="Smith"
<h3>What is SQL?</h3>
This is an acronym that means Structured Query Language that is used in handling data in a database.
Hence, we can see that from the attached image, there is a table that contains the details of customers and their various data such as their first and last names, credit limits, address, etc, and the GET_CREDIT_LIMIT procedure is shown above.
