Expert Solution & Answer
Chapter 8, Problem 3IQ
Explanation of Solution
Knowledge and experience having with ensuring data integrity:
- The data integrity denotes accuracy as well as uniformity of data kept in a
database , data warehouse or data mart. - It could be stated as a proxy for data quality.
- The data with integrity is meant to have a complete structure.
- The business rules, dates, relations, lineage as well as definitions of data should be complete.
- It is a process that verifies that data has remained unaltered in transit from source to destination.
- It denotes a measure of fidelity as well as validity of data object.
- The data must be reserved from modification, corruption or unauthorized disclosures...

7. Long-Distance CallsA long-distance provider charges the following rates for telephone calls:
Rate Category Rate per MinuteDaytime (6:00 a.m. through 5:59 p.m.) $0.07Evening (6:00 p.m. through 11:59 p.m.) $0.12Off-Peak (midnight through 5:59 a.m.) $0.05Write a GUI application that allows the user to select a rate category (from a set of radio buttons), and enter the number of minutes of the call into an Entry widget. An info dialog box should display the charge for the call.
Name and Address
The Name and Address Problem
Write a GUI program that displays your name and address when a button is clicked. The program’s window should appear as the sketch on the left side of Figure 13-61 when it runs. When the user clicks the Show Info button, the program should display your name and address, as shown in the sketch on the right of the figure.
Exercise 1 Function and Structure [30 pts]
Please debug the following program and answer the following questions. There is a cycle in a linked
list if some node in the list can be reached again by continuously following the next pointer.
#include
