The process of making changes to an information system to evolve its functionality, to accommodate changing business needs, or to migrate it to a different operating environment is known as _____________ maintenance.

Answers

Answer 1

Answer:

Corrective

Explanation:

An information system interacts with the overall system by receiving data in its raw forms and information in a usable format.

Information system can be defined as a set of components or computer systems, which is used to collect, store, and process data, as well as dissemination of information, knowledge, and distribution of digital products.

Generally, it is an integral part of human life because individuals, organizations, and institutions rely on information systems in order to perform their duties, functions or tasks and to manage their operations effectively. For example, all organizations make use of information systems for supply chain management, process financial accounts, manage their workforce, and as a marketing channels to reach their customers or potential customers.

Additionally, an information system comprises of five (5) main components;

1. Hardware.

2. Software.

3. Database.

4. Human resources.

5. Telecommunications.

Corrective maintenance can be defined as the process of making significant changes to an information system in order to evolve or transform its functionality, to accommodate and tolerate continuously changing business needs, or to migrate it to a different (new) operating environment.

This ultimately implies that, a corrective maintenance is performed so as to rectify (repair) faulty equipments or systems and to restore an underperforming resource to an operational or optimum status.

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;  

}

See attachment for complete program that include all methods that is required for the program to function.

Write a class Bug that models a bug moving along a horizontal line. The bug moves either to the right or left. Initially, the bug moves to the right, but it can turn to change its direction. In each move, its position changes by one unit in the current direction. Provide a constructor

Answers

Answer:

Following are the constructor to the given code:

Bug(int position) //defining a constructor that defines a integer parameters

{

       this.position = position;//use this key word to hold parameter value

       right = true;//defining a variable right that hold a boolean value

   }

Explanation:

In this code, a constructor is declared that defines integer parameters with it, Inside the constructor, this keyword is used to holds the "position" parameter value and defines a boolean variable "right" that holds a boolean value.

Full program:

public class Bug //declaring a class Bug

{

   private int position;//declaring integer variable position

   private boolean right;//declaring boolean variable

   public Bug(int position) //defining a parameterized constructor

   {

       this.position = position;//use this to hold position value

       right = true;//holding boolean value

   }

   public void turn() //defining a method turn

   {

       right = !right;//holding value

   }

   public void move() //defining method move

   {

       if(right)//use if to check boolean value

       {

           position++;//incrementing position value

       }  

       else//else block

       {

           position--;//decreasing position value

       }

   }

   public int getPosition()//defining method getPosition  

   {

       return position;//return position value

   }

   public static void main(String[] args) //main method

   {

       Bug bug = new Bug(10);//creating class object

       System.out.println("Expected = 10, Actual = " + bug.getPosition());//calling method with printing value

       bug.move();//calling method

       System.out.println("Expected = 11, Actual = " + bug.getPosition());//calling method with printing value

       bug.move();//calling method

       bug.move();//calling method

       bug.move();//calling method

       System.out.println("Expected = 14, Actual = " + bug.getPosition());//calling method with printing value

       bug.turn();//calling method

       bug.move();//calling method

       bug.move();//calling method

       System.out.println("Expected = 12, Actual = " + bug.getPosition());//calling method with printing value

       bug.turn();//calling method

       bug.move();//calling method

       System.out.println("Expected = 13, Actual = " + bug.getPosition());//calling method with printing 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.

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)

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.
