Chapter 5, 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...

Create a static function in C# where poachers appear and attempt to hunt animals. It gets the location of the closest animal to itself. Take account of that the animal also move too, so it should update the closest location (x, y) everytime it moves to a new location. Use winforms to show the movements of poachers.

You will need to implement the following: ➤ A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a Point (see java.awt.Point) in a PointCollection class (you need to build this). о The points need to be represented by circles. Below the drawing panel, you will need 5 buttons: о An input button to register your mouse to the drawing panel. ○ о о A show button to paint the points in your collection on the drawing panel. A button to shift all the points to the left by 50 pixels. The x position of the points is not allowed to go below zero. Another button to shift all the points to the right 50 pixels. The x position of the points cannot go further than the You can implement this GUI in any way you choose. I suggest using the BorderLayout for a panel containing the buttons, and a GridLayout to hold the drawing panel and button panels.…arrow_forwardIf a UDP datagram is sent from host A, port P to host B, port Q, but at host B there is no process listening to port Q, then B is to send back an ICMP Port Unreachable message to A.
