Q3
A relation Order(Order_ID, Date, Customer_ID, Customer_Name, Customer_City) has the primary key Order_ID. The functional dependencies are $\text{Order\_ID} \rightarrow \text{Date}, \text{Customer\_ID}$ and $\text{Customer\_ID} \rightarrow \text{Customer\_Name}, \text{Customer\_City}$ . To convert this relation into Third Normal Form (3NF), which of the following represents the correct set of decomposed relations?
Order(Order_ID, Date, Customer_ID) and Customer(Customer_ID, Customer_Name, Customer_City)
Order(Order_ID, Date) and Customer(Customer_ID, Customer_Name, Customer_City)
Order(Order_ID, Date, Customer_Name, Customer_City) and Customer(Customer_ID, Customer_Name)
Order(Order_ID, Date, Customer_ID) and Customer(Order_ID, Customer_Name, Customer_City)
Order(Order_ID, Date), Customer(Customer_ID, Customer_Name), and City(Customer_ID, Customer_City)
Q4
When designing a website with a large amount of content, which of the following is the best practice for content organization to enhance user experience?
Placing all information on a single, long scrolling page without navigation links.
Using a hierarchical structure with clear categories and a navigation menu.
Hiding important links at the bottom of the page to encourage users to read all the text.
Using completely different, unrelated color schemes and layouts for every single page.
Removing the search function to force users to browse manually.
