Interview "work simulation"

This exercise is designed to tell us something about your capabilities as a Java developer. The ultimate goal of it is spelled out in the main method of src/com/proquest/interview/phonebook/PhoneBookImpl. You will also need to know how to write a few very simple SQL queries.

The code is entirely self-contained: you should be able to load it up in Eclipse or another IDE and begin working immediately, without needing any other tools or libraries.

Implement the TODO comments to the best of your ability. In addition, you should be looking at how to improve this program. The DatabaseUtil class should not need to be significantly refactored, although you may do so as long as you do not destroy its functionality.

You should be able to fork this project, make your changes and send a pull request. If you have difficulty, you can simply download the project, change the files and send us a zip.

This exercise typically takes less than an hour, unless you choose to do significant refactoring. There are many possible approaches, and no single "right answer". But do be prepared to discuss the changes that you made.

Thank you!
