Information System for a Movie Theater
Information System for a Movie Theater
Problem Description
A local movie theater is interested in building a database information system. The database
will keep the information about the customers, sales, etc. The system will enable the
management to analyze the progress of the business, create financial reports, etc.
An important aspect of this project is to develop a web application that will allow the
customers to check the schedule of movies and purchase tickets on-line.
Database Design
We present the main entity types of this database. For each entity type, we provide some of
the corresponding attributes. Use this information in order to: (a) Build an Enhanced E-R
diagram; (b) Transform the Enhanced E-R diagram to a relational database. Identify the
primary key(s) and the foreign key(s) for each relation. Draw the relational integrality
constraints; (c) For each of the relations created, indicate its normal form. If the relation is
not in the 3NF, decompose it into 3NF relations.
1.
Customer: The main attributes are identification number, name, address, telephone
number, e-mail, etc.
2.
Employee: The main attributes are identification number, name, address, date of hire,
employment history, salary, etc.
3.
Movie: The main attributes are identification number, title, year of production, awards
won, description, actors, location, etc.
4.
Showroom: The main attributes are location, name, capacity, etc.
5.
Producer: The main attributes are identification number, name, address, contact
information, current balance, etc.
Note the following: (a) Awards won and Actors are multi-value attributes of the entity type
Movie. (b) Employment history is a multi-value attribute of the entity type Employee. (c) A
movie is played in at least one showroom and it is played at least once a day. When a movie
is assigned to a showroom, the following information is recorded: the timetable and the total
number of tickets available per show. (d) When a customer purchases tickets for a movie,
the following is recorded: ticket number, date, unit price, amount paid, and number of tickets
purchased. The number of tickets purchased reduces the total number of tickets available.
(e) Some of the customers choose to become members in order to buy tickets on-line. For
members, the following additional information is required: login name and password. (f)
When the movie theater purchases movies from a producer, the following information is
recorded: transaction number, purchase price, purchase date, payment due date, and
amount due.
Access Application Development
The following are some of the queries, forms, and reports one can create in order to
increase the functionality of the database:

expenses from salaries, the monthly expenses from purchasing new movies, and
the monthly earnings.
b.
Create a query that presents the total revenues, total expenses, and earnings
during the current year.
2.
Create a query that lists the five best movies of the current year. This classification is
based on the number of awards won.

10. Create a query that prompts for the name of a customer and returns details about the
ticket purchases made by the selected customer during the current month.
Forms:
1.
Create a user sign-in form together with a registration form for new users.
2.
Create the following data entry forms that are used for database administrative
functions: employees, movies, customers, movie timetables, etc. These forms allow the
user to add, update, and delete information about employees, movies, customers,
movie timetables, etc.
3.
Create a form that enables the user to browse through the financial reports created.
4.
Create a form that would enable the user to select a movie title from a combo box.
Insert a subform that presents the weekly timetable of the selected movie and the total
number of available tickets per show. Insert textboxes to present the following
information about the selected movie: production year, name of the producer, and a
description of the movie. Insert a command button that, when clicked-on, returns a list
with details about the awards won by the selected movie. Insert a command button that,
when clicked-on, returns details about the actors who perform in the movie. Insert a
command button that allows the user to purchase a ticket. When the user clicks-on this
button (a) the user sign-in form opens. If the user is not a member, the user registration
form opens. (b) Next, the data entry form opens to enable the user to purchase a ticket.
5.
Create a form that allows the user to browse through the information saved in this
database about actors. Insert a subform that presents details about the movies
performed in by the selected actor. Insert a subform that presents details about the
awards won by the selected actor.
