Answer: (D) Database design follows the twelve principles proffered by Dr. Edgar F. Codd
Explanation:
The relational database is basically based on the relational model of the data which is proposed by the Dr Edger F. codd and he mainly introduced the twelve basics principle of the database designing in the database system. He also contributed various valuable principle in the computer science.
The twelve principle are:
- The first rule of the relational database is the information rule as it represented all data or information
- Independence of the integrity
- Viewing various updating rule
- Logically treatment of various NULL value
- Independence of the physical database
- Distribution in-dependency
- Various delete, insert and update rules
- The overall logical description of the database are basically stored in the database directory
- There is no subversion rule
- There is guarantee accessing rule
- Proper rule for data language
- The relational database level actions

Answer:
Chernoff faces.
Explanation:
Chernoff faces is a data visualization technique that was developed by a statistician named Herman Chernoff. He introduced this data visualization technique to the world in 1973 to represent multivariate or multidimensional data containing at least eighteen (18) variables.
In Chernoff faces, each attribute is associated with a specific feature of a face (nose, eyes, ears, hair, mouth, and eyebrows), and the attribute value with respect to size, shape, orientation, colour and placement is used to determine the way a facial feature is expressed.
The Chernoff face is a technique designed and developed to help detect similarities between different items and discern subtle changes in facial expressions from the perspective of an observer.
Answer:
User application
Explanation:
A user application is a program that is created by using a standard software that is adjusted to the user's needs that can't be fulfilled by an existing system. According to this, the answer is that a user application utilizes standard business software, such as Microsoft Word or Microsoft Excel, which has been configured in a specific manner to enhance user productivity.
Answer:
The program in C is as follows:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main(){
int dice [1000];
int count [6]={0};
srand(time(0));
for (int i = 0; i < 1000; i++) {
dice[i] = (rand() %(6)) + 1;
count[dice[i]-1]++;
}
for (int i = 0; i < 6; i++) {
printf("%d %s %d %s",(i+1)," occurs ",count[i]," times");
printf("\n");
}
return 0;
}
Explanation:
This declares an array that hold each outcome
int dice [1000];
This declares an array that holds the count of each outcome
int count [6]={0};
This lets the program generate different random numbers
srand(time(0));
This loop is repeated 1000 times
for (int i = 0; i < 1000; i++) {
This generates an outcome between 1 and 6 (inclusive)
dice[i] = (rand() %(6)) + 1;
This counts the occurrence of each outcome
count[dice[i]-1]++; }
The following prints the occurrence of each outcome
for (int i = 0; i < 6; i++) {
printf("%d %s %d %s",(i+1)," occurs ",count[i]," times");
printf("\n"); }
