False: "Access to every table and field in a database is typically a need for every user."
How are the database's data accessible?Most of the time, it is not required for each user to have access to every table and field in a database. A primary key should be present in every table in a relational database. Each row in the table can be uniquely recognized by using the primary key, which is a column or group of columns.

A company makes a profit of $50 per software program and $35 per video game. The company can produce at most 200 software programs and at most 300 video games per week. Total production cannot exceed 425 items per week. How many items of each kind should be produced per week in order to maximize the profit?.
200 pieces of software and 235 games should be created each week in order to optimize earnings.
What does "software" actually mean?
Software is a set of guidelines, facts, or programs that direct computers to perform specific tasks.
The antithesis of software is hardware, which refers to a computer's external parts. The term "software" refers to all programs, scripts, and other operations that take place on a device.
Let
x ------> the number of software program
y -----> the number of video games
we know that
x ≤ 200 .......... inequality A
y ≤ 300 ......... inequality B
x + y ≤ 435 ......... inequality C
Using a graphing tool
The solution is the shaded area between the positive values fo x and y
see the attached figure
The vertices of the shaded area are
(0,0),(0,300),(135,300),(200,235),(200,0)
The profit function is equal to
P = 50x + 35y
Substitute the value of x and the value of y of each vertices in the profit function
For (0,300) ----- P = 50(0) + 35(300) = $10,500
For (135,300) ----- P = 50(135) + 35(300) = $17,250
For (200,235) ----- P = 50(200) + 35(235) = $18,225
For (200,0) ----- P = 50(200) + 35(0) = $10,000

Exercise 1.7.11: Integer Overflow points Let's Go! If an expression would evaluate to an int value outside of the allowed range, an integer overflow occurs. This could result in an incorrect value within the allowed range. In this program you will test for underflow and overflow in Java by adding 1 to the maximum value and subtracting 1 from the minimum value to see what happens to the output. Your output should include 4 items: • The minimum value for an integer. • The maximum value for an integer. • The minimum value subtracted by 1. • The maximum value with 1 added. What do the last two lines print out? Did this surprise you? What do you think it happening here? NOTE: Refer back to the previous example on Min and Max Values of Integers if you need to.
An integer overflow can result in the value wrapping and become negative, which goes against the program's premise and could produce unanticipated results.
Is there a fix for integer overflow?Using larger integer types, such as Java's long or C's long long int, can lessen the risk of integer overflow occurring in languages where it is possible. There are libraries made to handle arbitrary large numbers if you need to store anything even greater.
What would happen with a Java integer overflow?If it exceeds, it returns to the lowest value before continuing. If it falls below the maximum value, it returns there and continues. If you anticipate that this will happen frequently, think about utilising a datatype or object that can.

Exercise 4.3.7: Password Checker C
Write a program with a method called passeerCheck to return if the string is a valid password. The method should have the signature shown in the starter code.
The password must be at least 8 characters long and may only consist of letters and digits. To pass the autograder, you will need to print the boolean retum value from the
powardCheck method.
Hint: Consider creating a String that contains all the letters in the alphabet and a String that contains all digits. If the password has a charecter that isn't in one of those Strings.
then it's an illegitimate password
Answer:
here is an example of how you can implement the passerCheck method:
def passwerCheck(password: str) -> bool:
# Check if the password is at least 8 characters long
if len(password) < 8:
return False
# Create strings with all letters and all digits
all_letters = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'
all_digits = '0123456789'
# Check if the password consists only of letters and digits
for ch in password:
if ch not in all_letters and ch not in all_digits:
return False
# If the password passed all checks, return True
return True
# Test the passwerCheck method
print(passwerCheck("password")) # False
print(passwerCheck("password123")) # True
print(passwerCheck("12345678")) # False
print(passwerCheck("123456789")) # True
Explanation:
Here's an example implementation of the passwordCheck method in Java:
public class PasswordChecker {
public static void main(String[] args) {
String password = "Abc12345";
boolean isValid = passwordCheck(password);
System.out.println(isValid);
}
public static boolean passwordCheck(String password) {
String alphabet = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";
String digits = "0123456789";
// Check length
if (password.length() < 8) {
return false;
}
// Check characters
for (char c : password.toCharArray()) {
if (!alphabet.contains(Character.toString(c)) && !digits.contains(Character.toString(c))) {
return false;
}
}
return true;
}
}
In this example, the passwordCheck method takes a password as input and checks if it meets the given criteria. It first checks the length of the password, returning false if it's less than 8 characters.
Then, it iterates over each character in the password and checks if it belongs to the alphabet or digits strings. If a character is found that is not present in either of the strings, it means the password contains an illegitimate character, and false is returned.
If the password passes both length and character checks, the method returns true, indicating that the password is valid.

PROJECT STEPS
1. Beth owns a café chain with stores in four different cities. She wants to analyze her sales of and sales taxes associated with her store's most popular items.
Go to the Sales Summary worksheet.
Copy the contents of the range A6:A11 and paste them into the range A15:A20 so that Beth can compare the sales of and the sales taxes for the same products.
2. In cell B11, create a formula using the SUM function to total the values in the range B6:B10.
Using the Fill Handle, copy the formula in cell B11 into the range C11:F11.
3. Copy the contents of cell F5 to cell F14.
4. In cell E15, create a formula that multiplies the value in cell E6 (Latte sales in Baltimore) by the value in cell E14 (sales tax rate in Baltimore). Use a relative reference to cell E6 and an absolute reference to cell E14 in the formula.
Copy the formula you created in cell E15 to the range E16:E19 to determine the sales tax for each item sold in Beth's Baltimore branch.
5. Using the Fill Handle, copy the formula in cell B20 to the range C20:F20. 6. Beth wants to open a new store in a different city, and she wants to estimate what her expenses would be.
In cell A22, change the text to Average tax rate for all cities (without including a period at the end of the phrase).
7. In cell D22, create a formula that uses the AVERAGE function to identify the average tax rate for all cities from the values in the range B14:E14.
8. Beth would like to know which products resulted in her collecting the highest and lowest amounts of sales tax.
In cell A23, enter the text Highest tax paid across products (without including a period at the end of the phrase).
9. In cell D23, create a formula that uses the MAX function to identify the highest value in the range F15:F19.
10. In cell D24, create a formula that uses the MIN function to identify the lowest value in the range F15:F19.
11. Beth is interested in knowing how much revenue she generated from these popular items in total after deducting taxes.
In cell D25 create a formula that subtracts the value in cell F20 (total sales taxes collected) from the value in cell F11 (total sales).
12. Beth would also like the final revenue total to be rounded without decimal places. In cell D26, create a formula using the ROUND function that rounds the value in cell D25 to zero decimal places.
13. Because Beth already calculated the average tax rate for all cities in cell D22, the range A27:D27 is no longer necessary. Delete the cells in the range A27:D27 and shift the remaining cells up.
14. Cell A3 contains a note indicating this document is incomplete. As the worksheet is now finished, clear the contents of cell A3.
Your workbook should look like the Final Figure on the following page. Save your changes, close the workbook, then exit Excel. Follow the directions on the SAM website to submit your completed project.
