Instructions

Write a two-page executive summary for your boss explaining how a relational data solution can be applied to a current business problem or area for improvement. Assume that your boss knows nothing about relational database theory. The goal of this summary is to obtain your boss's approval to proceed with your stated project. Do not focus on technical aspects of a database management system. Focus on how the information will be captured, manipulated, managed, and shared, and the value the database brings to the organization. Include brief examples of how other industries (both domestic and international) have successfully used relational databases to increase efficiency.

Your paper must follow all APA Style Guide requirements. All sources must be properly cited using APA guidelines. Include an APA title page and an APA References page. Thes title page and References pages are in addition to the minimum of 2 pages of body text for your executive summary. In your summary you must include an introduction section with a heading, body text topic sections as apprporiate with headings, and a conclusion section with a heading. Note that APA requires 12 point Times Roman font throughout and 1" margins.

Submissions:

1. You should submit your well-organized Word document before the due date.
2. You should name your paper Yourname_shortpaper.docx.

Final Project

This assignment demonstrates your understanding of the concepts from the CMIS 141 class.
Before attempting this project, be sure you have completed all of the reading assignments, hands-on labs, discussions, and assignments to date.

1. Design, implement and test a Java application that will read a file containing data related to the passengers on the Titanic. The description of the file is shown below. The application should provide statistical results on the passengers including:

a. Total number of passengers on the Titanic
b. Percentage of passengers who perished on the Titanic
c. Percentage of Passengers who survived the sinking of the Titanic
d. Percentage passengers who survived the sinking of the Titanic as a function of the passenger class (e.g. 1,2,3)
e. A list of the names of passengers who were less than 10 years old who perished on the Titanic
f. The count of the number of passengers as a function of the first letter of their last name.
(e.g., A: 13, B:33 ...)
g. At least one additional statistical results you add to enhance the functionality

The following are some design criteria and specific requirements that need to be addressed:

a. Use command line arguments to send in the name of the Titanic file.

b. Use a 2D array to store the Titanic data. (Hint: You will probably need to store the array as String values and then convert to other types as needed since some data is null)

c. You should create at least 2 Java classes - Titanic and TestTitanic. You are welcome to create additional classes if you want to further separate the functionality.

d. You should create separate methods for each of the required functionality. (e.g. getTotalPassengers() will return the total number of passengers on the Titanic.)

e. A user-friendly and well-organized menu should be used for users to select which data to return. A sample menu is shown in run example. You are free to enhance your design and you should add additional menu items and functionality.

f. The menu system should be displayed at the command prompt, and continue to redisplay after results are returned or until Q is selected. If a user enters an invalid menu item, the system should redisplay the menu with a prompt asking them to enter a valid menu selection

g. The application should keep track of the elapsed time (in seconds) between once the application starts and when the user quits the program. After the program is exited, the application should provide a prompt thanking the user for trying the Titanic program and providing the total time elapsed.

Here is sample run:
