SE 450: Midterm Exam – Winter 2021
1. An instance variable belongs to the class in which it is declared.
ANSWER:
2. A constructor is a method that never returns anything, in fact it has void return type.
ANSWER:
3. A constructor is called the “default constructor” , if it has no parameters.
ANSWER:
4. A constructor is a method and therefore can be used through the dot operator, applied to
an instance of the class where it was declared.
ANSWER:
5. The following variable x is correctly used:
Point p1 = new Point ();
Point.x = 10;
ANSWER:
6. If a method is declared static, it cannot be called outside of its package.
ANSWER:
7. If we don’t prefix modifiers to a method, the method is only accessible within the same
package.
ANSWER:
8. An instance initializer is invoked before constructors.
ANSWER:
9. The keyword this allows you to reference the members of an object that will be created
only at runtime within the object itself.

Conceptual Database Design (ERD)
Conceptual Database Design (ERD)
With the given requirements for Cinema Chain database, draw Entity Relationship Diagram.
The requirements for database design are given in the following:
Warner and his brothers operate a cinema chain (Warner and Brothers Movies). He wants to build a database to use for forecasting demand for both the movies he shows and the food he sells as well as to track other critical information for his business.
He tells you that he has several cinemas and each cinema has between 1 and 20 theaters. Each CINEMA has a location, a unique name and a phone number. Each THEATER of a cinema isnumbered (like 1, 2, 3, …) and the theaters vary in terms of seating style, type of sound equipment and seating capacity.
MOVIEs are shown throughout the day starting at 11 am and finishing at 1 am. Some movies will be shown in multiple theaters and over time may switch theatres that they show in. For instance, Star Wars may originally be shown in the 3 largest theatres in a cinema but after 3 months it may be showing in just one of the smaller theaters. Of course, each theater is also used for a variety of movies over time. Warner is interested in knowing how many people, classified by adults and children, attend each showing of a movie. A SHOWING would be a specific run of a specific movie, for instance, Mission Impossible II at 11 am on Saturday Oct 28th in theater 3 at WB Cinemas. To estimate approximate ticket sales each showing is given a price code that describes the cost of children and adult tickets. For instance, morning weekend prices are $10 for adults and $7.50 for children. Besides the name of each movie, the length of the movie, the type of recording (Dolby surround sound, Dolby DTS, subtitles, etc.), and the rating of the movie are recorded in the database. Warner also wants to record any awards the movie has won (e.g. Oscar for best picture, 1997, etc.).
Each cinema has a manager and several other EMPLOYEEs. Most employees are trained by another employee when they are hired. Warner needs to know the name, address, Social Security Number and phone number for all of his employees. He also wants to be certain he knows who is the manager of what cinema, who trained each employee, and at which cinema each employee works.
No employee works at more than one cinema and some employees do not work at a cinema at all (i.e. the IS department). All cinemas have one and only one manager.
In order to track FOOD RECEIPTs Warner has the manager at each cinema enter in the total receipts each cinema makes for beverages, popcorn and candy at the end of every day. (Their cash registers are not automated or linked to the database yet. Only one total food receipt in a day for a cinema is recorded in database, not every food receipt for each transaction.).
Your task is to create ER Diagram based on the above requirements.
Use software either Lucidchart or Visio to draw ERD.

Applicant Essay for an Internship in Cybersecurity
More and more hiring actions start with a written essay from job candidates followed by a telephone “screening” interview. For this week’s discussion topic, you will take on the role of an applicant for an internship in a CISO organization. You are at the first stage in the application process — writing the essay. You have been asked to respond to ONE of the following questions:
1. Why should a large company (>1000 employees) adopt and use COBIT 5 to manage IT security risks?
2. How does compliance with the four Payment Card Industry (PCI) Standards help an e-Commerce company manage IT security risks?
The application review committee is a group of managers (both technical and non-technical) who depend upon IT security to protect their business operations (including intellectual property, company strategic and financial information, and customer data). The purpose of the essay is two fold. First, the review committee is looking for the ability to think critically and analyze a relevant problem. Second, the review committee is looking for applicants who can communicate effectively in writing for both technical and non-technical audiences.
