Define the terms candidate key and primary key. Explain the difference between a primary key and a candidate key.

Shkiper50 [21]

Explanation:

Both Primary Key and Candidate Key are the attributes that are used to access tuples from a table. These (Primary key and Candidate key) are also can be used to create a relationship between two tables.

A Candidate Key can be any column or a combination of columns that can qualify as a unique key in the database. Each Candidate Key can qualify as a Primary Key.
A Primary Key is a column or a combination of columns that uniquely identify a record. The primary key is a minimal super key, so there is one and only one primary key in any relationship.

The main difference between them is that a primary key is unique but there can be many candidate keys.

I hope you find this information useful and interesting! Good luck!

Determine the distance between point (x1, y1) and point (x2, y2), and assign the result to points Distance. The calculation is:

Nadusha1986 [10]

Question:

Snapshot of the question has been attached to this response.

Answer:

import java.util.Scanner;

import java.lang.Math;

public class CoordinateGeometry{

public static void main(String []args){

double x1 = 1.0;

double y1 = 2.0;

double x2 = 1.0;

double y2 = 5.0;

double pointsDistance = 0.0;

//Declare a variable to hold the result of (x2 - x1)²

double x;

//Solve (x2 - x1)^2 and store result in the variable x

x = Math.pow(x2 - x1, 2);

//Declare a variable to hold the result of (y2 - y1)²

double y;

//Solve (y2 - y1)^2 and store result in the variable y

y = Math.pow(y2 - y1, 2);

//Now pointsDistance = SquareRootOf(x + y)

pointsDistance = Math.sqrt(x + y);

System.out.println("Points distance: ");

System.out.println(pointsDistance);

return;

}

Sample Output:

Points distance:

3.0

Explanation:

The above code has been written in Java and it contains comments explaining important lines of the code. Please go through the comments.

List the five parts of a system.describe them.

dem82 [27]

The five main parts of a system are:

1. The CPU
The CPU is the brain of the computer. It is the main part that does all th thinking and processing.

2. RAM
which stands for Random Access Memory. As implied in its name, it can be accessed at random times by the CPU. When you open a program, all the scripts and codes that are running need to be run of a separate memory bank. Thus, the RAM takes part.

3. Drives
Hard Drives, SSDs, USB Drives, and SD cards are all forms of main computer memory. That is where the computer stores the OS, your files, and its instructions.

4. Inputs/Outputs
By inputs and outputs i mean hardware, like Speakers (ouput), Monitors (output), Keyboard (input), and Mouse (input).

5. OS
The OS is the Operating System (e.g. Windows, Linux, Mac), which is the main instructions for the computer. It is what makes your computer usable.
