Objective
The objective of this assignment is

o To make you familiar with queue and linked list data structure and programming techniques to
implement queue as linked list.


GOOD LUCK
Marks: 20
Suppose three movies (Harry Potter, English Vinglish and Tekken) are on display in a cinema. Three different
counters are distributing tickets for each movie. To purchase a particular movie ticket, you are required to standin the respective movie counter queue.

Considering the above scenario, write a C++ program which asks a user to choose the movie for which he/she
would like to purchase a Ticket. While choosing the movie ticket, user should be asked to enter his/her social
group [F for female, M for male and K for kids].
The required program functionalities should be:
 Take input for all the three movies.
 Display the total number of visitors for each movie.
 Display total revenue of cinema and total revenue of each movie (Suppose price of one ticket is 650/-).
 Display the best business earning movie of the cinema.
 Check the popularity of each movie amongst social groups (females, males or kids).
Solution Guidelines:

1) To purchase the movie ticket, viewer must have to stand in the queue. The length of the queue can vary so you have
to implement queue as link list.
2) Create a class named Viewer (Node class); this class should create a node for each ticket. This class should define two
private data members, social group and Next pointer. A constructor, getter and setter functions for each data member
should also be defined in this class.
Note: While getting the value for social group, restrict the user to only enter ‘f’ or ‘F’ for female, ‘m’ or’ M’ for male
and ‘k’ or ‘K’ for kids.
3) Create another class named Mov_Que (List class); to create a queue for each movie, this class should define three
variables, Front pointer, Rear pointer and counter. The class should also define the following functions:
a) Constructor(): Default constructor of the class.
b) Destructor(): Destructor to destroy the memory gained by the use of new operator.
c) add_Ticket(): This method should enter the new ticket purchased at the rear.
d) Total_Visitors(): This method should return the total number of visitors of movie.
e) Total_Revenue(): This method should return the total revenue of the movie.
f) Popularity(): This method should check the popularity of the movie amongst social group, whether the movie is
popular among males, females or kids.
4) In main() function of the program, create three objects of the class Mov_Que which will act like three
counters at cinema. These objects should be able to perform all the required functionalities mentioned in
the question statement.
5) To get the idea about exact output of program, see Demo.wmv file attached with assignment file.

Objectives

The objectives of this assignment are,

1.      Giving the idea of the most common tool used for designing database systems i.e. Data Flow Diagram. It is used to design systems graphically and expresses different details of system in different DFD levels.

2.      To become familiar with the flow of data between different processes and to hide complexities in any given system.

Assignment

Consider a real world scenario of a university system. We are going to develop a security information system for employees so that there may be no chances of error or illegal access of an employee record or account. To complete this system we will divide this whole project in small assignment chunks (probably 4 to 5) and will try to cover every phase of the database development life cycle from scratch to implementation (SQL Queries). Scenario of the Security information system is given below.

Scenario:

The top management of the university wants to computerize the university employee’s records for security reason. The security information system will comprise of three sub applications.

1.      Fingerprint system (deployed through a biometric device)

2.      Online Employee Record Management (ERM) that will be a web based application deployed on a central server and access able through LAN

3.      Live Activity Monitoring System (LAMS) deployed through security camera (CCTVs) installed on various location in university premises.

Detail of each application is given below:

Fingerprint system:

To achieve this task the management wants to fix an automated fingerprint identification system for employee’s attendance. This system automatically matches fingerprints against a database of known prints. Attendance system uses biometrics to guarantee the accuracy in reporting. Attendance system works by having an employee place their finger on a small scanner upon entering and exiting the office, the attendance record is stored in the database. This information can later be checked by the management to track the employee’s check in, checkout times and location as well.

Online ERM:

To guarantee security, the employee’s are provided with a web account. Employees are provided with the user name and password so that no one can access his / her record. Using their account, employees can mark attendance, apply for leave, apply for loan, manage his/her bank account or see salary slip. Employee can also generate a new password by using the “Forgot your password?” link on the login page.

Live Activity Monitoring System (LAMS):

To better enhance the security system, management wants to install the security cameras to monitor the employee’s activities more closely, to keep an eye on precious assets and properties of the university. With the help of security cameras unauthorized and illegal activities are controlled. The security cameras capture images and record videos. These records are stored in the database.  The management can view all the details about their employees at any time to monitor the productivity and job related skills of employees. Further than case use the information to ensure that he/she might not indulge in any immoral activities.

Note that all the three applications share a central database (as shown in figure-1), deployed on a dedicated database server.

Task Description:

This Assignment is starting phase and in this assignment you will focus only on the tasks given below:

Task-1:

Part1. You are required to identify all the processes in the system.   (4 Marks)

Part2. Find out all the external entities interacting with the system. (4 Marks)

Task-2:

Part1. Create a Context level DFD                                                     (4 Marks)

Part2. Create Detailed DFD of the system                                           (8 Marks)

Note: In Task-2 Part2 decompose the DFD up to level-1 i.e. after context draw level-0 and then further decompose up to level-1

Important things to consider:

Ø  As happens in real world that everyone visualize a problem in different way so the solutions of all students should be according to their own thinking not taken from some source.

Ø  As this is preliminary phase of our system so it is recommended that you identify as much processes and their relationships as you can (some of them may be eliminated in coming assignments).
