Consider a Sales table with the following columns, and it contains sales data for multiple years:SaleIDSaleDateCustomerIDAmountSaleIDSaleDateCustomerIDAmount12023-01-1510150022023-03-2210230032023-07-1010345042024-02-0510470052024-05-1810535062024-09-30106600Question:The Sales table is horizontally partitioned using sales date into Sales_2023 and Sales_2024 partitions.Which of the following statements are true? (One or more choices are correct)

Which of the following statements about data warehouses are true? (One or more choices are correct)

Consider the following two tables: Orders and Customers.Orders table:OrderIDCustomerIDOrderDateAmount11012024-01-1525021022024-02-2045031012024-03-10300Customers table:CustomerIDFirstNameLastName101AliceSmith102BobJohnsonA view called CustomerOrders is created using the SQL below which combines data from these two tables, showing each order along with the customer’s name.CREATE VIEW CustomerOrders ASSELECT O.OrderID, C.FirstName, C.LastName, O.OrderDate, O.AmountFROM  Orders O JOIN  Customers C ON O.CustomerID = C.CustomerID;The CustomerOrders view looks like this:OrderIDFirstNameLastNameOrderDateAmount1AliceSmith2024-01-152502BobJohnson2024-02-204503AliceSmith2024-03-10300Question:Given the CustomerOrders view, which of the following statements are true? (One or more choices are correct)
