Expert Solution & Answer
Chapter 5.8, Problem 4ARQ
Explanation of Solution
A database contains all the necessary information that is required for processing the business.
- The database is not useful for the business user since the contents that are present in them are structured in an unorganized way.
- The data stored in the database is present in the raw form and hence database is not ideal for the users.
Four elements of database application:
The four elements of database applications that are listed below:
- Forms
- Reports
- Queries
- Application Programs.
Purpose of the elements of database application:
The purpose of the each element is described below:
Forms:
The data present in the database can be viewed, inserted, updated and deleted using the elements.
Let us consider the example:
- Consider the student mark that needs to updates in the database.
- The form can be used to enter the marks scored by the user and the mark entered by the user can be viewed by the user through forms.
- Consider the mark that is entered by the user needs to be corrected and it can be updated through forms.
- Any student record that is not required can be deleted through forms.
Reports:
The data that are stored in the database are represented in the structural format by performing sorting, grouping, filtering and through other data manipulation process.
Let us consider the example:
A student record whose score can be viewed from highest to lowest order by using the sorting operation.
Queries:
The data values can be retrieved based on the search made by the user.
Let us consider the example:
A student whose score is greater than “90” can be viewed using the query given by the user.
Application Programs:
Application programs are used to provide security to the data, maintaining the consistency of the data and to process special purpose.
Let us consider the example:
The student data can be corrected only by the teacher who enters it the data is secured in such a way no student cannot modify the data present in the database...

1.[30 pts] Computers generate color pictures on a video screen or liquid crystal display by
mixing three different colors of light: red, green, and blue. Imagine a simple scheme, with
three different lights, each of which can be turned on or off, projecting onto a glass screen:
We can create eight different colors based on the absence (0) or presence (1) of light
sources R,G and B:

Each of these colors can be represented as a bit vector of length 3, and we can apply
Boolean operations to them.
a. The complement of a color is formed by turning off the lights that are on and turning
on the lights that are off. What would be the complement of each of the eight colors
listed above?
b. Describe the effect of applying Boolean operations on the following colors:
Λ
1. Red(100) ^ Magenta(101)= Blue(001)
2. Bue(001) | Green(010)=
3. Yellow(100) & Cyan(011)=

Methods (Ch6) - Review
1. (The MyRoot method) Below is a manual implementation of the Math.sqrt() method in Java.
There are two methods, method #1 which calculates the square root for positive integers, and
method #2, which calculates the square root of positive doubles (also works for integers).
public class SquareRoot {
public static void main(String[] args) {
}
// implement a loop of your choice here
// Method that calculates the square root of integer variables
public static double myRoot(int number) {
double root;
root=number/2;
double root old;
do {
root old root;
root (root_old+number/root_old)/2;
} while (Math.abs(root_old-root)>1.8E-6);
return root;
}
// Method that calculates the square root of double variables
public static double myRoot(double number) {
double root;
root number/2;

do {
root old root;
root (root_old+number/root_old)/2;
while (Math.abs (root_old-root)>1.0E-6);
