g Why do database systems support concurrent execution of transactions, despite the extra effort needed to ensure that concurrent execution does not cause any problems
Answer:
Explanation:
To maintain data consistency and integrity in a large multi-user system, transactions are completed concurrently with the aid of concurrency management techniques.
The following are some of the benefits of concurrent transaction processing and execution versus serial transaction processing and/or execution:
Improved Resource Usage:
A transaction frequently combines both CPU and Input/output activities, resulting in better resource usage. Computers have the ability to run disks and CPUs in parallel. As a result, transactions can also be executed in parallel, with one employing the usage of the CPU and the other using the disk. As a result, resources are better used than in serial transaction processing and execution.
Improved throughput:
Running transactions in parallel has an immediate impact of increasing throughput since a greater number of transactions can be completed in the same period of time.
Lower/shorter waiting time:
Reduced wait time: When transactions are processed sequentially and serially, a short transaction is forced to wait for a longer transaction. Because transactions usually affect distinct portions of the database. As such, it's best if they happen at the same time i.e it is run concurrently.
The characteristics listed above are critical to a system's performance.
Thus, It is obvious that the benefits of concurrency exceed the extra programming work necessary to execute transactions concurrently. As a result, database systems must handle concurrent transactions despite the additional work necessary since it is worthwhile.
Briefly explain the mapping of human thinking to artificial intelligence components?
Answer:
The technique is mind mapping and involves visual representation of ideas and information which makes it easier to remember and memorize facts even in complex subjects. Here is an example of a mind map with the essential elements of AI and the industries where Artificial Intelligence is applied.
Artificial is a term utilized to elaborate something that isn't natural or we can say unnatural (opposite to natural). Whereas, definition of "intelligence" is a bit complex as the term enclose many different and specific corporeal tasks, like learning, problem-solving, reasoning, perception, and language understanding.
Mind mapping technique involves the representation of information and ideas visually which concludes in much easier and friendly way to remember and imprints the facts even in complex subjects.
Below is the example in how the A.I applies in fields like health care, educations, financials etc.

Consider the following statements, taken from three different Jack programs. In each one of these programs, the identifier foo represents a different thing: let x = 5 + foo - a // program 1. Here foo represents a simple variable. let y = foo[12] - 3 // program 2. Here foo represents an array. let z = 2 * foo.val() // program 3. Here foo represents an object. Suppose that we are parsing any one of these statements (we don’t know which), and that the current token is foo. What kind of parser do we need to determine if we have a simple variable, an array reference or a method call?
Answer:
instanceOf
Explanation:
The parser that would be best suited for this scenario would be the instanceOf keyword, which is part of the javaParser class. This keyword allows you to check if a variable is a simple variable, an array reference or a method call through an IF statement. If it is equal to the compared type it will return a boolean value of True, otherwise it will return False. This keyword is used in Java and Javascript to check the type of the variables in scenarios such as this one.

Explanation:
In this lab, you complete a C++ program that uses an array to store data for the village of Marengo.
The program is described in Chapter 8, Exercise 5, in Programming Logic and Design. The program should allow the user to enter each household size and determine the mean and median household size in Marengo. The program should output the mean and median household size in Marengo. The file provided for this lab contains the necessary variable declarations and input statements. You need to write the code that sorts the household sizes in ascending order using a bubble sort and then prints the mean and median household size in Marengo. Comments in the code tell you where to write your statements.
Instructions
Make sure that the file HouseholdSize.cpp is selected and open.
Write the bubble sort.
Output the mean and median household size in Marengo.
Execute the program by clicking the Run button and the bottom of the screen.
Enter the following input, and ensure the output is correct. Household sizes: 4, 1, 2, 4, 3, 3, 2, 2, 2, 4, 5, 6 followed by 999 to exit the program.
Here is my code so far. I need help finishing it (printing the mean & median, etc). Thanks so much:
// HouseholdSize.cpp - This program uses a bubble sort to arrange up to 300 household sizes in
// descending order and then prints the mean and median household size.
// Input: Interactive.
// Output: Mean and median household size.
#include
#include
using namespace std;
int main()
{
// Declare variables.
const int SIZE = 300; // Number of household sizes
int householdSizes[SIZE]; // Array used to store 300 household sizes
int x;
int limit = SIZE;
int householdSize = 0;
int pairsToCompare;
bool switchOccurred;
int temp;
double sum = 0;
double mean = 0;
double median = 0;
// Input household size
cout << "Enter household size or 999 to quit: ";
cin >> householdSize;
// This is the work done in the fillArray() function
x = 0;
while(x < limit && householdSize != 999)
{
// Place value in array.
householdSizes[x] = householdSize;
// Calculate total of household sizes
sum+= householdSizes[x];
x++; // Get ready for next input item.
cout << "Enter household size or 999 to quit: ";
cin >> householdSize;
} // End of input loop.
limit = x;
// Find the mean
// This is the work done in the sortArray() function
pairsToCompare = limit - 1;
switchOccured = true;
while(switchOccured == true)
{
x = 0;
switchOccured == false;
while (x < pairsToCompare)
{
if(householdSizes[x]) > householdSizes[x+1])
{
//perform switch
}
x++;
}
pairsToCompare--;
}
// This is the work done in the displayArray() function
//Print the mean
// Find the median
median = (limit-1) / 2;
if (limit % 2 ==0)
{
cout << "Median is: " << (householdSizes[(int)median] + householdSizes[(int)median + 1]) / 2.0 << endl;
}
else {
// Print the median household size
}
// Print the median
return 0;
} // End of main function
Answer:
For the mean, do the following:
mean = sum/limit;
cout<<"Mean: "<<mean;
For the median do the following:
for(int i = 0; i<limit; i++) {
for(int j = i+1; j<limit; j++){
if(householdSizes[j] < householdSizes[i]){
temp = householdSizes[i];
householdSizes[i] = householdSizes[j];
householdSizes[j] = temp; } } }
median= (householdSizes[(limit-1)/2]+householdSizes[1+(limit-1)/2])/2.0;
if((limit - 1)%2==0){
median = householdSizes[limit/2];
}
cout<<endl<<"Median: "<<median;
Explanation:
The bubble sort algorithm in your program is not well implemented;
So, I replaced the one in your program with another.
Also, some variable declarations were removed (as they were no longer needed) --- See attachment for complete program
Calculate mean
mean = sum/limit;
Print mean
cout<<"Mean: "<<mean;
Iterate through each element
for(int i = 0; i<limit; i++) {
Iterate through every other elements forward
for(int j = i+1; j<limit; j++){
Compare both elements
if(householdSizes[j] < householdSizes[i]){
Reposition the elements if not properly sorted
temp = householdSizes[i];
householdSizes[i] = householdSizes[j];
householdSizes[j] = temp; } } }
Calculate the median for even elements
median= (householdSizes[(limit-1)/2]+householdSizes[1+(limit-1)/2])/2.0;
Calculate the median for odd elements
if((limit - 1)%2==0){
median = householdSizes[limit/2];
}
Print median
cout<<endl<<"Median: "<<median;

Explanation:
Passing an int argument into the method named print ;
print() ; Here, the print method has no argument as it is empty
print()+5; Here also, the print method has no argument and adding +5 is an invalid syntax.
print("5") ; Here, print takes in an argument, however, the argument is a string due to the fact that 5 is enclosed by quotation marks.
print(5) ; Here, the integer is 5 is passed to the print method.
