Assignments for Online Learning Web Application

Please create two views

1) For Admin - to upload the assignments:  

You can store the assignments in SQL server as BLOB. 

2) For Users- to download the assignment:

Display the assignments from sql server and give option for download.

 

You can use flags in database whether user downloaded assignment or not. It can be useful when user comes back and visit the page.

Other MVC concepts remain same. Instead of storing assignments in database you can store them in file server or files(application path). Store the URL(path) in sql server and refer it in download.
