Aggregate Functions: SQL has some built-in functions and they are called as aggregate functions. SQL contains five built-in functions. They are: SUM – This function is used to add values from the particular column. Syntax: SELECT SUM(column_Name) FROM table_Name; COUNT – This is used to count the number of rows for the particular column. Syntax: SELECT COUNT(column_Name) FROM table_Name; MAX – This function is used to get the maximum value from the column. Syntax: SELECT MAX(column_Name) FROM table_Name; MIN – This function is used to get the minimum value from the column. Syntax: SELECT MIN(column_Name) FROM table_Name; AVG – This function is used to get the average of all the values from the column. Syntax: SELECT AVG(column_Name) FROM table_Name; DISTINCT Keyword: “DISTINCT” keyword is used to avoid redundant data (removing duplicate values) from a column. The syntax for “DISTINCT” keyword is as follows: SELECT DISTINCT column_Name FROM table_Name;

Question

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. GPA points would have been arrived at by adding 4 points for each credit hour of A, 3 points for each credit hour of…
