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:

To begin you will create a College python class that keeps track of the csollege's unique id number, name, address, phone number, maximum students, and average tuition cost. Once you have built the College class, you will write a program that stores College objects in a dictionary while using the College's unique id number as the key. The program should display a menu in this order that lets the user: 1) Add a new College 2) Look up a College 4) Delete an existing College 5) Change an existing College's name, address, phone number, maximum guests, and average tuition cost. 6) Exit the programarrow_forwardShow all the workarrow_forward
