A relation is in 3NF if, for every non-trivial functional dependency X→Y, which of the following conditions hold?

Which of the following best describes a row-level trigger?

What is the primary purpose of creating an index on a database table?  

Consider the relation Sells (bar, beer, price) And suppose we added this tuple-based check   CHECK (bar = ‘Joe”s Bar’ OR price

Consider two tables, Sells and Beers, with the following schema:   CREATE TABLE Beers (    name VARCHAR(50) PRIMARY KEY,    manf VARCHAR(50));   CREATE TABLE Sells (    bar VARCHAR(50),    beer VARCHAR(50),    price DECIMAL(5,2),    FOREIGN KEY (beer) REFERENCES Beers(name));   What happens if the following INSERT statement is executed? INSERT INTO Beers(name, manf) VALUES (‘Bud Light’, ‘Anheuser’);  

Consider the relation Sells (bar, beer, price) and the following view that has been created: CREATE VIEW ExpensiveBeers AS SELECT DISTINCT beer, price FROM Sells WHERE price > 5.00;   What happens when you attempt to update the ExpensiveBeers view?  

Given this trigger:  CREATE TRIGGER RoundPriceBEFORE INSERT ON SellsFOR EACH ROWSET NEW.price = ROUND(NEW.price);     A User attempts to execute the following statement on Sells (Bar, Beer, Price):     INSERT INTO Sells (bar, beer, price) VALUES (‘Joe”s Bar’, ‘Corona’, 4.75); What will happen to the price value inserted into the Sells table?    

How does the timing of execution differ between constraints and triggers in a database?

Consider two tables, Sells and Beers, with the following schema:   CREATE TABLE Beers (    name VARCHAR(50) PRIMARY KEY,    manf VARCHAR(50));   CREATE TABLE Sells (    bar VARCHAR(50),    beer VARCHAR(50),    price DECIMAL(5,2),    FOREIGN KEY (beer) REFERENCES Beers(name));   What happens if the Beer table had a record of Bud Light and the following Delete statement is executed? Delete from Sells Where beer = ‘ Bud Light’
