Multi-part question:

Part 1:

Use MySQL Workbench to create an EER model for a database that stores information about the downloads that users make. (When you create the EER model, it will be given a default name of mydb. For this exercise, it’s not necessary to change this name.) Define the tables that are necessary to implement this data structure:

Each user must have an email address, first name, and last name.

Each user can have one or more downloads.

Each download must have a filename and download date/time.

Each product can be related to one or more downloads.

Each product must have a name.

When you’re done defining the tables, create a diagram for the database. Then, use the diagram to define the required relationships. When you do that, be sure to use the relationship button that uses existing columns.

Part 2:

Create a view named order_item_products that returns columns from the Orders, Order_Items, and Products tables.

This view should return these columns from the Orders table: order_id, order_date, tax_amount, and ship_date.

This view should return the product_name column from the Products table.

This view should return these columns from the Order_Items table: item_price, discount_amount, final_price (the discount amount subtracted from the item price), quantity, and item_total (the calculated total for the item).

Part 3:

Write a SELECT statement that uses the view that you created in part 2 to get total sales for the five best selling products. Sort the result set by the order_total column in descending sequence.

Answer:

Apple Keynote is presentation Software

The correct option is C

Explanation:

Now let explain each option

Word processor:

Word processor is incorrect because it is used to type text, format it add tables and figures, For example MS Word

Spread Sheet:

Spread Sheet is incorrect as it is used for calculation. Like MS Excel

Presentation:

Key tone is a presentation software. it is used to make presentation and add animation and transition to it.

Database

Database is incorrect because databases are used for storing data. Not for presentation.

Answer:

There is massive importance if you want to study information study.

It can help you understand the data, organize, and process the data, using which we can generate and share information.

Explanation:

It largely depends on your interest and requirement, but a better knowledge or clue about information systems may help analyze the data especially if you want to become a data scientist, machine learning, Artificial intelligence or deep learning, etc.

It can help you understand the data, organize, and process the data, using which we can generate and share information.

A great understanding of information systems may exponentially increase the productivity, growth, performance, and profit of the company.

Most Professions get exposed to information Systems no matter what their career objective is, as it may help in having better decision making based on the information they get through data.

So, yes!

There is a massive importance if you want to study information study.

Answer:

P₂ = 0.5 W

Explanation:

It is given that,

The attenuation of a signal is -10 dB.

We need to find the final signal power if it was originally  5 W.

Using attenuation for signal :

[tex]dB=10\text{log}_{10}(\dfrac{P_2}{P_1})[/tex]

Put dB = -10, P₁ = 5 W

Put all the values,

[tex]-10=10\text{log}_{10}(\dfrac{P_2}{5})\\\\-1=\text{log}_{10}(\dfrac{P_2}{5})\\\\0.1=\dfrac{P_2}{5}\\\\P_2=5\times 0.1\\\\P_2=0.5\ W[/tex]

So, the final signal power is 0.5 W.

The final signal power if it was originally 5W is; 0.5 W

We are given;

Formula for attenuation signal is;

dB = 10log_10_ (P2/P1)

Where P2 is final signal power

Thus;

-10 = 10log_10_(P2/5)

-10/-10 = log_10_(P2/5)

-1 = log_10_(P2/5)

0.1 = P2/5

P2 = 0.1 × 5

P2 = 0.5 W

Explanation:

Answer:

By modifying the hidden form values that is in a local copy of the company web page

Explanation:

In a situation were the hacker successful change the price of the items he/she purchased through the web site of the company's in which the company web server as well as the company Oracle database were not compromised directly which means that the most likely method in which the attacker used to modified the sale price of the items he/she purchased was by modifying the HIDDEN FORM VALUE that was in the local copy of the company web page making it easy for the HIDDEN FORM VALUE to be vulnerable to the hacker because the hidden form value did not store the company server side information or data but only store the company software state information which is why HIDDEN FORM VALUE should not be trusted.

Answer:

class Car:

   def __init__(self, model_year, purchase_price):

       self.model_year = model_year

       self.purchase_price = purchase_price

       self.current_year = 0

       self.current_value = 0

   def set_current_year(self, year):

       self.current_year = year

   def calc_current_value(self, current_year):

       if self.current_year == 0:

           return "Must first input the current year"

       depreciation_rate = 0.15

       car_age = current_year - self.model_year

       self.current_value = round(self.purchase_price - (car_age * (self.purchase_price * 0.15)))

   def print_info(self):

       print("Car's information:")

       print(f"Model year: {self.model_year}")

       print(f"Purchase price: {self.purchase_price}")

       if self.current_value > 0:

           print(f"Current value: {self.current_value}")

       else:

           print("Current value: Unknown")

Explanation:

The python program above defines the class "Car" that accepts the model year and purchase price of an instance. The class has a set method for the current year variable that is used to calculate and update the current value variable of the object. The print_info method prints the car model year, purchase price and its current value after nth years.

Answer:

TEMPEST.

Explanation:

TEMPEST is an acronym for Telecommunications Electronics Materials Protected from Emanating Spurious Transmissions and it is a secret (classified) project of the government of the United States of America that originated with its military in the 1960s based on the study of security with respect to telecommunication devices emitting Electromagnetic Radiation (EMR).

Hence, the U.S. military standard for computer security is known as TEMPEST.

The main purpose of the Telecommunications Electronics Materials Protected from Emanating Spurious Transmissions (TEMPEST) is to prevent the theft, compromise or interception of informations that are being transmitted on various telecommunications devices through the use of Electromagnetic Radiation (EMR).

Answer:

import java.util.Scanner;

public class Countdown {

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

int n;

System.out.print("Please enter a number to start: ");

n = input.nextInt();

System.out.print(countdown(n));

}

public static String countdown(int number) {

if(number>0) {     return " "+number+countdown(number-1);    }

   else    {        return " Blastoff!";    }

}

}

Explanation:

The main method begins here

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

This declares an integer variable n

int n;

This prompts user for a number

System.out.print("Please enter a number to start: ");

This gets user input n

n = input.nextInt();

This calls the countdown function

System.out.print(countdown(n));

}

The countdown function begins here

public static String countdown(int number) {

This is the base case where input number is greater than 0

if(number>0) {     return " "+number+countdown(number-1);    }

This ends the recursion

   else    {        return " Blastoff!";    }

}
