i). Justify whether the above relation requires normalization. 2 Marks
ii). Determine in what normal form the relation is? Briefly explain. 3 Marks
iii). Where possible, identify and illustrate the three update anomalies from the relation. 6 Marks

12 Marks
v). How many resultant relations and what are their cardinalities and degrees at the end of 3NF? 7 Marks
vi). Define the Oracle PL/SQL Scripts to create the resultant relations
The relation Order_Item_Detail requires normalization because it contains redundant data and violates the first normal form (1NF). For example, the Item_ID, Item_Name, Item_Unit_Price, and Item_Description repeat for multiple Order_ID's, which can lead to data inconsistency and anomalies when the data is updated or deleted.
How to convey the informationii). The relation Order_Item_Detail is in the first normal form (1NF), as it meets the requirement of having a single value in each cell of the relation.
iii). The three update anomalies from the relation are:
Insert Anomaly: If we want to insert a new order for an item that does not already exist in the relation, we will have to insert the same item information multiple times.
Update Anomaly: If we want to update the item information, such as the price of an item, we would have to update the same information in multiple rows, leading to potential inconsistencies in the data.
Delete Anomaly: If we want to delete an order, we may end up deleting the item information as well, which may not be what we intended.
iv). To normalize the relation to 3NF, we need to follow the following steps:
Step 1: Create a new relation called Item_Detail with the following attributes:
Item_ID
Item_Name
Item_Unit_Price
Item_Description
Step 2: Create a new relation called Order_Detail with the following attributes:
Order_ID
Order_Date
Item_ID (Foreign Key referencing the Item_ID in Item_Detail)
Step 3: Remove the Item_Name, Item_Unit_Price, and Item_Description attributes from the Order_Item_Detail relation, and replace it with the foreign key, Item_ID, referencing the primary key in the Item_Detail relation.
The resulting relation Order_Detail will have the following structure:
Order_Detail
Order_ID Order_Date Item_ID
11 16-Nov-2022 101
11 16-Nov-2022 102
11 16-Nov-2022 103

101 Beef 1Kg 1,000 Beef Protein
102 Chicken 1Kg 1,250 Chicken Protein
103 Pork 1Kg 1,800 Pig Protein
108 Veal 1Kg 2,500 Deer Protein
v). After normalizing the relation to 3NF, we end up with two relations, Order_Detail and Item_Detail. The cardinality of the Order_Detail relation is 5 (number of rows), and the degree is 3 (number of columns). The cardinality of the Item_Detail relation is 4 (number of rows), and the degree is 4 (number of columns).
vi). The Oracle PL/SQL Scripts to create the resultant relations are as follows:

A sawmill uses a system of blowers to remove sawdust from the working areas of the mill. The flow in the ducts must be controlled to be sure that enough air is being pulled out to keep the air in the mill clean.
The airflow is monitored using a pitot tube mounted in the center of the large duct leading to the dust collection system and main blower. When the mill was first opened, the airflow in the building was checked, and the correct position of the liquid in the pitot was marked. The blower is checked daily to keep the liquid at the same position in the tube.
Several months later, the safety officer said that the air in the mill was too dusty. The area manager checked the pitot tube, and the liquid was exactly at the original mark. The fan speed was lower than before. The dust filters had been changed the week before.

Variables have been declared for you, and the input statements and output statements have been written. Read them over carefully before you proceed to the next step.
Design the logic, and write the rest of the program using a switch statement.
Execute the program by clicking the Run button at the bottom of the screen entering the following as input:
Employee’s name: Jeanne Hanson
Employee’s salary: 70000.00
Employee’s performance rating: 2
Confirm that your output matches the following:

cout << " Employee Salary: "<< numSalary << endl;
cout << "Employee Rating: " << numPerformanceRate << endl;
cout << "Employee Bonus: $" << bonus << endl;
return 0;
}
what am I doing wrong?
Answer:
You need to write the code that calculates the bonus based on the employee's performance rating and salary. This calculation should be done inside the switch statement and the bonus variable should be updated with the correct value. You can use the numPerformanceRate and numSalary variables to determine the bonus, and the BONUS_1, BONUS_2, BONUS_3, and BONUS_4 constants to calculate the bonus.
Explanation:
switch (numPerformanceRate) {
case RATING_1:
bonus = numSalary * BONUS_1;

case RATING_2:
bonus = numSalary * BONUS_2;
break;
case RATING_3:
bonus = numSalary * BONUS_3;

Write a method mostFrequentDigit that returns the digit value that occurs most frequently in a number. Example: The number 669260267 contains: one 0, two 2s, four 6es, one 7, and one 9. mostFrequentDigit(669260267) returns 6. If there is a tie, return the digit with the lower value. mostFrequentDigit(57135203) returns 3.
Answer:
public static int mostFrequentDigit(int num) {
int[] count = new int[10];
while (num > 0) {
int digit = num % 10;
count[digit]++;
num = num / 10;
}
int maxCount = 0;
int mostFrequent = 0;
for (int i = 0; i < count.length; i++) {
if (count[i] > maxCount) {
maxCount = count[i];
mostFrequent = i;
}
}
return mostFrequent;
}
Explanation:
The mostFrequentDigit method takes in an integer num and returns the digit value that occurs most frequently in num.
The method first declares an array count of size 10 to keep track of the frequency of each digit (0-9).Next, the method uses a while loop to repeatedly divide num by 10 and keep track of the remainder (which represents the last digit of num) in each iteration. For each iteration, the frequency of the last digit is incremented in the count array.After the while loop, the method uses a for loop to iterate through the count array and keep track of the digit with the maximum frequency in the variables maxCount and mostFrequent.Finally, the method returns the value of mostFrequent, which represents the digit that occurs most frequently in num.So, for the example mostFrequentDigit(669260267), the method would return 6, since 6 is the digit that occurs the most frequently in the number.
What's the best way to automatically space many vector objects evenly?
Layer palette
I Align tool
Manually measure using rulers
Distribute tool
Answer:
Explanation:
The best way to automatically space many vector objects evenly in most vector graphic design software would be to use alignment tools or distribute spacing options.
For example, in Adobe Illustrator, you can select multiple objects, go to the "Align" panel, and choose the "Distribute Horizontally" or "Distribute Vertically" option to distribute the objects evenly based on the spacing between their edges. Some software also has "Distribute Space" options which allow you to set a specific amount of space between objects.
In Inkscape, you can use the "Distribute Nodes Equidistantly" feature in the "Extensions" menu to evenly distribute objects along a path.
It's always a good idea to experiment with different options in your software to determine what works best for your specific project.

A radio tower casts an 8-foot-long shadow at the same time that a vertical yardstick casts a shadow one half inch long. If the triangles formed by the objects and their shadows are similar, how tall is the radio tower?.
If the triangles formed by the objects and their shadows are similar, the height of the radio tower is 576 feet.
What is the height?Height is a measure of vertical distance, either vertical extent.
Given that, the radio tower casts a shadow 8 feet long. At the same time that a vertical yardstick casts a shadow half an inch long
To find: the height of the radio tower
Let "x" be the height of the radio tower
Length of the shadow of the tower = 8 feet
Length of the shadow of stick = 1/2 inch
Length of the shadow of the stick = 0.0416 feet
Length of vertical yard stick = 3 feet (since 1 yard = 3 feet )
Height of the tower/length of the shadow power = length of yardstick/ length of shadow stick.
x/8 = 3/ 0.0416
x = 8 x 72.11
x = 576
Therefore, the height of the radio tower is 576 feet approximately.

Phishing is a type of cyberattack where an attacker sends a fraudulent email to many recipients in an attempt to trick them into providing sensitive information such as login credentials, credit card numbers, or other personal information. The email is designed to look like it comes from a legitimate source, such as a bank or an e-commerce site, and typically contains a link that takes the victimised by a phoney website that imitates the genuine one.
The victim is prompted to provide personal data once they arrive at the bogus website. The information is then collected by the attacker and can be used for various types of fraudulent activities, such as identity theft, financial fraud, and other forms of cybercrime.
Phishing attacks can be difficult to detect because the email and website may look very convincing. It is important to be cautious when clicking links in emails and to verify the authenticity of any website that asks for personal information.

**DUE TOMORROW, NEED ANSWER ASAP**
NASA has asked you to evaluate a number of proposals for telescopes. These proposals include information about where the telescope would be built and what wavelengths it intends to observe at. Based only on these factors, evaluate whether NASA should consider funding each proposal. Justify your recommendations. (Some telescopes may have more than one "correct" answer depending on how you justify it).
a.) An ultraviolet telescope in space
b.) An optical telescope in a remote location in Michigan's upper peninsula
c.) A radio telescope in the Mojave desert in Arizona
d.) An x-ray telescope in the Andes mountains in Chile
e.) An optical telescope in space
Answer:
Explanation:
a.) An ultraviolet telescope in space: This proposal would likely be worth considering for funding by NASA. Ultraviolet light is not easily observable from the ground because the Earth's atmosphere blocks much of it. By placing a ultraviolet telescope in space, it would have a clear view of the universe and would be able to gather important data about stars, galaxies, and other celestial objects. In addition, studying ultraviolet light can provide insights into the evolution of stars and galaxies, making this proposal a valuable contribution to astronomical research.
b.) An optical telescope in a remote location in Michigan's upper peninsula: This proposal is also worth considering for funding. Optical telescopes are used to observe visible light and can provide important information about the structure and composition of celestial objects. The remote location in Michigan's upper peninsula would likely provide good observing conditions, with minimal light pollution and good atmospheric stability. However, it is important to note that there are many other optical telescopes already in operation, so the proposed telescope should have a unique focus or capability in order to stand out from existing instruments.
c.) A radio telescope in the Mojave desert in Arizona: This proposal is worth considering for funding by NASA. Radio telescopes are used to observe radio waves emitted by celestial objects, providing important information about the composition and behavior of stars, galaxies, and other astronomical objects. The Mojave desert in Arizona is a good location for a radio telescope, as it has minimal radio frequency interference and a dry, stable atmosphere, making it ideal for radio observations.
d.) An x-ray telescope in the Andes mountains in Chile: This proposal is also worth considering for funding. X-ray telescopes are used to observe X-rays emitted by celestial objects, providing important information about the high-energy processes in stars and galaxies. The Andes mountains in Chile offer excellent observing conditions, with minimal atmospheric absorption of X-rays and good access to the southern sky.
e.) An optical telescope in space: This proposal is also worth considering for funding. Like ultraviolet telescopes, optical telescopes in space would have a clear view of the universe and would be able to gather important data about stars, galaxies, and other celestial objects. By observing optical light from space, astronomers can avoid the distortions and limitations of the Earth's atmosphere and gain a better understanding of the universe.
In conclusion, all of the proposals have potential value, but the ultimate decision on funding should be based on a comprehensive evaluation of each proposal, including factors such as cost, scientific impact, technical feasibility, and the overall priority of the proposed mission.

Suppose a program takes 10000 seconds to run on single processor system. However, the parallel version of the program takes only 3200 seconds to run on a four processor (four core) system.
a) Find the speed up of the parallel program over the serial one.
b) The parallel program runs for a while in a serial mode and then in a parallel node. Find out the time the program spends in the serial mode of execution.
Answer:
a. Speed up = 3.125
b. Time spent in serial mode = 6800 seconds
Explanation:
a) The speed up of the parallel program can be found by dividing the time it takes to run on the serial system by the time it takes to run on the parallel system.
Speed up = Time to run on serial system / Time to run on parallel system
Speed up = 10000 seconds / 3200 seconds
Speed up = 3.125
b) To find the time the program spends in the serial mode of execution, we can subtract the time it takes to run on the parallel system from the total time it takes to run on the serial system.
Time spent in serial mode = Total time to run on serial system - Time to run on parallel system
Time spent in serial mode = 10000 seconds - 3200 seconds
Time spent in serial mode = 6800 seconds
