2. load_friendsdb
This function does the reverse of save_friendsdb -- it takes a single argument, filename, and opens that specified file for
reading. Then it reads the file one line at a time and creates a new friends database to return. Like in the previous
function, each line will contain a friend's name followed by a tab, then the friend's height, and then a newline.
Sample calls should look like this:
>>> load friendsdb("friendsdb.tsv")
[{'name': ' bimmy', 'height': 600}, {'name': 'Ian Donald Calvin Euclid Zappa', height': 175}]
Create an application which can access a database.
Create a database with an application user, user specific for your application to use, and 1 table of a couple of fields properly indexed. Grant permissions for the user to access the table. (submit .SQL file)
Create a simple application, language of your choice, (BE languages only, no JS or Node) which can do the following operations: (submit source code file):
Connect using the application user created above.
Insert into the table, and select from the table using a WHERE clause, where all fields are parameterized.
Display results of the select.
Use a simple web server API interface for data input and output, which can be accessed via local browser or curl.
