The problem Library Management (Online book issuing app) solves

The user can now search books by their Name, Semester, Branch and issue them by just a click.
They can see the availability of books and also which books they have issued in the 'Your Issued books'. The main problem it solves that the student can take the book at any day (at library time) after issuing the book so it does not makes the library crowded which disturbs the nature of library and the students studying there.

Challenges we ran into

As there is limit of issuing books from library it was a challenge to restrict user from issuing for more than 3 and at the same time update the stock of the number of books in library in database. Also one idea of pushing notification to the user at the deadline of returning the book was challenging which we were not able to figure it out.
