Hello!
Before Social Media , Many people liked the old classical way and they had there own way to communicate with people. With social media everything changed . Companies started to grow and real face to face communication was shrinking slowly . Kids locked themselves in there rooms to text friends and play games instead of playing outside. But technology does have a good affect for example if it wasn't for technology i wouldn't be able to help you right now ! If it wasn't for social media Wendy's wouldn't be able to Roast people . And contact over the phone would be limited .
HOPE I HELPED HAVE A BLESSED DAY!!
Answer:
Changing the customer number on a record in the Orders table to a number that does not match a customer number in the customer table would violate referential integrity.
If deletes do not cascade, deleting a customer that has orders would violate referential integrity.
If deletes cascade, customer can be deleted and all orders for that customer will automatically be deleted.
C. ">" denotes the end of an element. For instance <b>Hello!</b> or <hr />
