Textbook Question

Chapter 3, Problem 51E

Use a combination of code reading, execution of methods, breakpoints, and single stepping to familiarize yourself with the Mai1Item and MailClient classes. Note that we have not yet discussed enough for you to understand the implementation of the MailServer class, so you can ignore this for now. (You can, of course, look at it if you feel adventurous, but don't be surprised if you find it slightly baffling ...) Explain in writing how the Mai 101 lent and Mail Item classes interact. Draw object diagrams as part of your explanations.

The assignment here is to write an app using a database named CIT321 with a collection named students; we will provide a CSV file of the data. You need to use Vue.js to display 2 pages. You should know that this assignment is similar, all too similar in fact, to the cars4sale2 example in the lecture notes for Vue.js 2. You should study that program first. If you figure out cars4sale2, then program 6 will be extremely straightforward. It is not my intent do drop a ton of new material here in the last few days of class. The database contains 51 documents. The first rows of the CSV file look like this: sid last_name 1 Astaire first_name Humphrey CIT major hrs_attempted gpa_points 10 34 2 Bacall Katharine EET 40 128 3 Bergman Bette EET 42 97 4 Bogart Cary CIT 11 33 5 Brando James WEB 59 183 6 Cagney Marlon CIT 13 40 GPA is calculated as gpa_points divided by hrs_attempted.
