Answer:
(a) Supplier
Explanation:
In database design, two tables are linked together using a FOREIGN KEY. A foreign key is formed from one or more columns of one table that reference or match another key (often called a primary key) in another table. In other words, when a column or a combination of columns on one table points to a primary key of another table, the column(s) will specify the foreign key.
PS: A primary key is used to make each entry of a table unique.
In the given tables - Supplier, Product, Country - since the Supplier table has a column called CountryId referencing the CountryId column of the Country table, then CountryId is a primary key in Country table but a foreign key in Supplier table.
Therefore, the CREATE TABLE statement(s) of the Supplier table must specify a foreign key.
A database management system often reads and writes data in a database, and makes sure there is consistency and availability. The supplier table's CREATE TABLE statement(s) must specify a FOREIGN KEY.
The database system often guards data when a lot of transactions is taking place. it often hinders multiple transactions with the same data at the same time.The Select SQL statement does not alter any database data. A supplier database is made up of different list of service, product or materials providers who can meet orders quickly.

Using a loop and indexed addressing, write code that rotates the members of a 32-bit integer array forward one position. The value at the end of the array must wrap around to the ?rst position. For example, the array [10,20,30,40] would be transformed into [40,10,20,30].
//begin class definition
public class Rotator{
//main method to execute the program
public static void main(String []args){
//create and initialize an array with hypothetical values
int [] arr = {10, 20, 30, 40};
//create a new array that will hold the rotated values
//it should have the same length as the original array
int [] new_arr = new int[arr.length];
//loop through the original array up until the
//penultimate value which is given by 'arr.length - 1'
for(int i = 0; i < arr.length - 1; i++ ){
//at each cycle, put the element of the
//original array into the new array
//one index higher than its index in the
//original array.
new_arr[i + 1] = arr[i];
}
//Now put the last element of the original array
//into the zeroth index of the new array
new_arr[0] = arr[arr.length - 1];
//print out the new array in a nice format
System.out.print("[ ");
for(int j = 0; j < new_arr.length; j++){
System.out.print(new_arr[j] + " ");
}
System.out.print("]");
}

Your disaster recovery plan calls for tape backups stored at a different location. The location is a safe deposit box at the local bank. Because of this, the disaster recovery plan specifies that you choose a method that uses the fewest tapes, but also allows you to quickly back up and restore files. Which backup strategy would best meet the disaster recovery plan for tape backups?
Store Physical Backup Media Offsite. Like data stored in the cloud, offline data stored on physical media is susceptible to unauthorized access. Offsite media storage helps significantly reduce the possibility of theft and physical damage to your media assets from fires, floods and natural disasters.
An incremental backup is one in which successive copies of the data contain only the portion that has changed since the preceding backup copy was made. ... Incremental backups are often desirable as they reduce storage space usage, and are quicker to perform than differential backups.
In the following cell, we've loaded the text of Pride and Prejudice by Jane Austen, split it into individual words, and stored these words in an array p_and_p_words. Using a for loop, assign longer_than_five to the number of words in the novel that are more than 5 letters long. Hint: You can find the number of letters in a word with the len function.
Answer:
Explanation:
Since the array is not provided, I created a Python function that takes in the array and loops through it counting all of the words that are longer than 5. Then it returns the variable longer_than_five. To test this function I created an array of words based on the synapse of Pride and Prejudice. The output can be seen in the attached picture below.
def countWords(p_and_p_words):
longer_than_five = 0
for word in p_and_p_words:
if len(word) > 5:
longer_than_five += 1
return longer_than_five

What is meant by a balanced budget?
A. inflows are greater than outflows
B. inflows are less than outflows
C. inflows are equal to income
D.inflows are greater than or equal to outflows.
Answer:
D.inflows are greater than or equal to outflows.
Explanation:
A budget is a financial plan used for the estimation of revenue and expenditures of an individual, organization or government for a specified period of time, often one year. Budgets are usually compiled, analyzed and re-evaluated on periodic basis.
A balanced budget is a type of budget in which inflows are greater than or equal to outflows. Thus, when cash inflows (income) is greater than or equal to cash outflows (expenses), a budget is said to be balanced.
The first step of the budgeting process is to prepare a list of each type of income and expense that will be integrated or infused into the budget.
This ultimately implies that, before preparing a budget, it is of utmost importance to know total income (inflows) and expenses (outflows).
The final step to be made by the management of an organization in the financial decision-making process is to make necessary adjustments to the budget.
In conclusion, the benefits of having a budget is that it aids in setting goals, earmarking revenues and resources, measuring outcomes and planning against contingencies. It is typically used by individuals, government, organizations or companies due to the fact that, it's tied directly to the strategy and tactics of a company on an annual basis. Also, it is used to set a budget for marketing efforts while anticipating on informations about the company.

Suppose that you are asked to modify the Stack class to add a new operation max() that returns the current maximum of the stack comparable objects. Assume that pop and push operations are currently implemented using array a as follows, where item is a String and n is the size of the stack. Note: if x andy are objects of the same type, use x.compareTo(y) to compare the objects x and y public void push String item ) { [n++] = iten; } public String pop { return al--n]; } Implement the max operation in two ways, by writing a new method using array a (in 8.1), or updating push and pop methods to track max as the stack is changed (in 8.2). Q8.1 Implement method maxi 5 Points Write a method max() using Out) space and Oin) running time. public String max() {...} Enter your answer here Q8.2 Update push() and popo 5 Points Write a method max() using On) space and 011) run time. You may update the push and pop methods as needed public void push {...} public String pop() {...} public String max() {...}
Answer:
Following are the code to the given points:
Explanation:
For point 8.1:
public String max()//defining a method max
{
String maxVal=null;//defining a string variable that holds a value
for(int x=0;x<n;x++)
{
if(maxVal==null || a[i].compareTo(maxVal)>0)//defining if blok to comare the value
{
maxVal=a[i];//holding value in maxVal variable
}
}
return maxVal;//return maxVal variable value
}
For point 8.2:
public void push(String item)//defining a method push that accepts item value in a parameter
{
a[n]=item;//defining an array to hold item value
if(n==0 || item.compareTo(maxVals[n-1])>0)//use if to comare item value
{
maxVals[n]=item;//holding item value in maxVals variable
}
else
{
maxVals[n]=maxVals[n-1];//decreasing the maxVals value
}
n++;//incrementing n value
}
public String pop()//defining a method pop
{
return a[--n];//use return value
}
public String max()//defining a method max
{
return maxVals[n-1];//return max value
}
In the first point, the max method is declared that compares the string and returns its max value.In the second point, the push, pop, and max method are declared that works with their respective names like insert, remove and find max and after that, they return its value.
