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
Answers
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.
Write a program to sort the (name, age, score) tuples by descending order where name is string, age and score are numbers. The sort criteria is: 1: Sort based on name 2: Then sort based on age 3: Then sort by score The priority is that name < age < score. If the following tuples are given as input to the program: [('John', '20', '91'), ('Jason', '21', '85'), ('Jony', '17', '91'), ('Johny', '17', '93'), ('Tom', '19', '80')]\
Answers
Answer:
The program in Python is as follows:
from operator import itemgetter
m = int(input("Number of records: "))
print("Name, Age, Score")
my_list =[]
for i in range(m):
user_details = input()
my_list.append(tuple((user_details.split(","))))
my_list.sort(key = itemgetter(0, 1, 2))
print("Sorted: ", my_list)
Explanation:
This imports the operator function from itemgetter
from operator import itemgetter
This gets the number of records, m
m = int(input("Number of records: "))
This prints the format of input
print("Name, Age, Score")
This initializes the list of tuples
my_list =[]
This iterates through m
for i in range(m):
This gets the details of each person
user_details = input()
This appends the details to the tuple
my_list.append(tuple((user_details.split(","))))
This sorts the tuple
my_list.sort(key = itemgetter(0, 1, 2))
This prints the sorted tuple
print("Sorted: ", my_list)

Define a method calcPyramidVolume with double data type parameters baseLength, baseWidth, and pyramidHeight, that returns as a double the volume of a pyramid with a rectangular base. calcPyramidVolume() calls the given calcBaseArea() method in the calculation.
Answers
Answer:
The method in C++ is as follows:
double calcPyramidVolume(double baseLength, double baseWidth, double pyramidHeight){
double baseArea = calcBaseArea(baseLength, baseWidth);
double volume = baseArea * pyramidHeight;
return volume;
}
Explanation:
This defines the calcPyramidVolume method
double calcPyramidVolume(double baseLength, double baseWidth, double pyramidHeight){
This calls the calcBaseArea method to calculate the base area of the pyramid
double baseArea = calcBaseArea(baseLength, baseWidth);
This calculates the volume
double volume = baseArea * pyramidHeight;
This returns the volume
return volume;
}

cin >> second;//input value
cout << "Enter third number: ";//print message
cin >> third;//input value
while(notDone == true)//defining a loop to check the value

int temp = second;//defining temp to hold second value
second = third;//holding second value in third variable
third = temp;//holding temp value in third variable
}
cout << "Smallest: " << first << endl;//print smallest value
cout << "Next smallest: " << second << endl;//print Next smallest value
cout << "Largest: " << third << endl;////print Largest value
cout << "Enter any letter to continue or done to quit: ";//print message
cin >> repeat;//holding string value
if (repeat == SENTINEL)
{
notDone = false;//holding bool value

In which SDLC step does the company translate broad, user-oriented systems requirements into the detailed specifications used to create a fully developed system
Answers
Answer:
Physical design.
Explanation:
Systems development life cycle (SDLC) is a strategic process that involves determining the overall system architecture, which is typically comprised of hardware, end users, physical processing components, software, and the communication channel that will effectively and efficiently satisfy the essential requirements of the system.
The system inputs and outputs is typically designed along with a plan of how the system's features will be navigated.
Basically, system design is divided into two (2) categories and these includes;
I. Logical design.
II. Physical design.
Furthermore, the design of service systems involves the process of planning, creating infrastructure, building communication, organizing staffs and standardization of a system so as to improve its quality and business relationships between the service provider and its clients.
In the physical design of systems development life cycle (SDLC), broad, user-oriented systems requirements are obtained from end users by companies and then translated into the detailed specifications that would be used to create a fully developed system.

Answers
Answer:
Explanation:
The following code is written in Python. It creates a Person class and creates the constructor which takes in the name of the person for that instance, as well as a greeting method which outputs the desired "Hi, my name is" string with the name of that person. The output of the code can be seen in the attached picture below. I have created a person object called John and called the greeting method so that you can see the output.
class Person:
name = ''
def __init__(self, name):
self.name = name
def greeting(self):
print('Hi, my name is ' + self.name)
The code containing the Person class definition and the greeting is found in the attached image
The Person class has a single instance field name that stores the name of the person.
The instance initializer, __init__, accepts an argument, name, and saves the value in the name attribute of the Person class.
The Person class also has a greeting method that is called by the main code segment. The main code segment creates a Person object, and calls it in the print function to display the greeting with the person's name.

Declare a typedef struct named jumper_t that will have four parts: character array name that is 16 in length, double array of tries that is N_TRIES in length, double best_jump, double deviation 2. Write one line to declare an array variable, named jlist of the above struct type, with a length of ten. No initialization required.

} jumper_t;
The declaration of jlist is:
jumper_t jlist[10];
Explanation:
This defines the typedef structure
typedef struct jumper_t {
The following declares the variables as stated in the question
char name[16];
double tries[N_TRIES];
double best_jump;
double deviation;
}
This ends the typedef definition
jumper_t;
