Library System Project - Data Analysis, Design, and Implementation

This project outlines the design and implementation of a library system, covering various aspects of software engineering. It begins with project planning, including a Gantt chart and Trello board. The project details requirements documentation, focusing on automated late fine calculations and user notifications. It presents a use case diagram and textual descriptions for the 'Reserve Book' function, detailing actors, pre-conditions, triggers, and alternative paths. The project also includes a sequence diagram, class diagram, activity diagram, and user interface designs for login, loans, and item interfaces. Finally, it provides test case generation, focusing on verifying login, availability checking, and member validation, along with a bibliography of relevant software engineering resources. The project is designed to provide a comprehensive overview of library system development from planning through to testing.

Task 2 – Requirements Documentation
The librarian late fine should be calculated automatically in the information system after
entering the details off the user and a notification message should be popped up showing the
amount that is due. The manual calculation of the late fine can cause error in the system and
thus it is designed to automate the management process.

ASSIGNMENT – LIBRARY SYSTEM
Summary
The user can select the reserve book option
to borrow a book from the library. The
reserve option is followed by many of the
sub processes such as verification of the
user, paying late fine for returning the book
after the due date.
Actors
The primary actor of the library
management system are the user, librarian
and the information system.
Pre-conditions
For borrowing a book from the library the
user should have a valid user account and
should successfully pass the verification
process. The book. The book searched by
the user from the catalogue should also be
available in the library and can be allocated
to the user requesting for it.
Triggers
The user needs to select a book for
borrowing it from the library.
Basic course of
Events
The user logs in into the system and
searched for the book and selects the book
he/ she wants. The reserve book option is
checked and on selection of the option the
information system verification the details
of the user. The user can cancel the

reservation and reserve from remote
location. For remote reservation the user
needs to physically visit the library to pick
up the book. The librarian allocated the
book and assigns a due date for returning
the book. The user needs to return the book
within the due date or else a fine is charged.
For the next borrow of book the user needs
to pay the fine.
Alternative Paths
The user can visit the library and if the book
is not available he can put a hold and wait
for the book to be released.
Post-Conditions
After the book has been allocated the
database of the information system is
updated with the details of the book and the
return date for maintaining a transparency
on the system.
Business Rules
If the late fine is greater than $25 then the
account of the borrower needs to be
suspended. The borrower account can be
created by the librarian and the details of the
borrower should be recorded.
Notes Before issuing the book the librarian should
check the details of the other users putting a

allocated to the allocated to the user first
claimed for the book.
