Comprehensive Library System Project: Analysis, Design, and Testing

This project presents a comprehensive analysis and design of a library system. It begins with a Gantt chart for project management and then defines functional requirements, such as the 'Pay Fine' use case. The project includes a detailed use case diagram illustrating interactions within the library system, followed by a specific use case for borrowing items, complete with actors, pre-conditions, triggers, basic events, alternative paths, and post-conditions. Sequence and class diagrams are provided to visually represent system processes and structure. An activity diagram depicts a student searching for and placing a hold on a book. Furthermore, the project presents user interface designs for library administration, loans, member interfaces, and borrowable items. Finally, the project concludes with test cases based on the activity diagram, covering user authorization, book availability checks, loan status checks, and hold request completion.

Task 1
1. The Gantt chart for the whole assignment project is,
2.
Task 2
The given scenario is ‘Pay Fine’.
It is assumed that a borrower has borrowed one or more books from the library and have not returned yet.
The fines have been accumulated for the borrower and it is more than $25. So, the borrower’s account has
been suspended until the fine is being cleared.
The ‘Pay Fine’ is a functional requirement for the system. So, the requirement description is,
A borrower needs to pay fine if the borrower has not returned borrowed items past the expected return
date. If the system finds that the items borrowed by a borrower has not been returned yet, it must calculate
the fine accumulated for the borrowed items. If the accumulated sum is more than $25, the borrower
account will be suspended and the borrower will not be able to borrow new items until the fine is cleared.
The borrower must give the fine manually to a librarian. The librarian will revoke the ‘active’ status of
the borrower account by marking due fines and cleared.
Task 3
The use case diagram for the Library system is given below.

Task 4
Name Borrow Item
Version 1.0
Goal It allows a borrower to borrow an item from the library.
Summary The use case represents the borrowing function. The library has books, study
materials and other electronic items to borrow. A Borrower borrows a book or
other items from the library. The librarian approves the loan and provides a
due date for returning the item. The user may return the item to the library
within the due date or may have to pay fine if the due date is crossed.
Actors Borrower is the primary actor. Librarian is the secondary actor.
Pre-conditions Borrower must have an active borrower account with the library system.
Triggers Borrower wants to borrow an item from the library.
Basic course of Events 1. Borrower asks for the approval of the librarian for borrowing a new
item.
2. System checks if the borrower is eligible to borrow an item or not.
3. Librarian receives the request and checks whether the item is on
reserve or not. If the item is available and the borrower has an active
status then the librarian approves the request and gives a due date to
return the item.

4. Borrower returns the item within the due date. It is represented by the
‘Return Item’ use case.
If the borrower does not return an item within the given due date,
then the borrower needs to pay fine. It is represented by the extended
use case, ‘Pay Fine’.
Alternative Paths From step 3. If the item is found to be marked as reserved item and it is not
possible to allocate the item to the borrower, then the librarian cancels the
request.
Post-Conditions The borrower will have a borrowed item with a due date to return.
Business Rules The library system must allow a borrower to borrow an item from the library
with the help of a librarian.
Notes NA.
