The document discusses various database concepts, including SQL queries, joins, triggers, sequences, and subqueries, providing examples and possible query outputs. It emphasizes the correct use of SQL operators like UNION, INTERSECT, and MINUS, as well as the implications of using triggers in relational databases. Additionally, it contains hypothetical questions and answers pertaining to database operations and the expected results from different SQL statements.

1. this is about databases questions , maybe i miss copy some
option D, if ABC there are all incorrecct please type D after that
question thank you
Suppose that a PRODUCT table contains two attributes,

The problems for this chapter use a database for a simple
department store that sells items to customers and wants to keep
track of the invoices, the selling price (if an item is on sale),
and the sales tax (7%) to be collected on some items. Every
customer and invoice are assigned unique numbers. All items
have a Universal Product Code (UPC) number and bar-code
assigned to each unique item. Food and non-carbonated
beverages are not taxed, but clothing, home goods, and most
other items are.
The structure of the tables are described in the following crows

The problems for this chapter use a database for a simple
department store that sells items to customers and wants to keep
track of the invoices, the selling price (if an item is on sale),
and the sales tax (7%) to be collected on some items. Every
customer and invoice are assigned unique numbers. All items

42. have a Universal Product Code (UPC) number and bar-code
assigned to each unique item. Food and non-carbonated
beverages are not taxed, but clothing, home goods, and most
other items are.
The structure of the tables are described in the following crows
foot ERD:
Sample Data for the tables follow:
Customer
Customer_Id
Customer_
FirstName
Customer_
LastName
Customer_
Address
Customer_
City
