    Instructions to Solve Assignments

    The purpose of assignments is to provide you with application-oriented exercise to strength the concepts. It is expected that students will solve the assignments themselves. Following rules will apply during the evaluation of assignment.

    • Cheating from any source will result in zero marks in the assignment.
    • In case of cheating from any other student, both students will be awarded “F” grade in the course.
    • In case of question No. 03 direct copy and paste from the research paper will be awarded zero marks.
    • No assignment after due date will be accepted.

    Question No. 1 [Marks 15]
    Consider a library management system of Virtual University of Pakistan which maintains a list of books for students, teaching assistants and faculty members to borrow. Each user has its own username and password. Note that it should be fourteen characters long at least. Users should not be allowed to use the system without providing a valid username and password. Whenever a user login into the system, he is provided with an interface to search the required book. After searching the book, he/she selects it for borrow. After entering details, the book is released for the user for fourteen days. After fourteen days either he/she will have to return the book or apply for re-issue. The book should be issued second time as per round robin policy i.e. if no other student/faculty is waiting, the book will be re-issued else it will be available for next student waiting for the book. You can use circular link list for this purpose. Faculty members can also borrow the books according to same rules mentioned above. He/she also follows the same process i.e. he/she selects the book, enters information and clicks submit button. Finally, the book is issued for entire semester. After semester, either he/she should return the book or apply for re-issue. For re-issue, same round robin policy will be applied.
    As system is used by many users at all levels (including new comer students), it should have high usability and there should be no performance issues.

    Keeping in view the quality attributes of Software requirement document, identify the quality issues with the requirements given above. For convenience, one example is given below in tabular form below. Identify and mention five other issues.
