UNI Library Information System – Assignment Planning, Requirements Documentation, And Diagrams

Task 1: Project planning

The information systems are very important in all organizations and institutions since they are used to safely keep record of the organization’s functions and this enable easy storage and retrieval of information that is required at any given time.

However the UNI library information system is a system that is used in the library to keep the record of the books, exams, borrowers’ details, borrowed items details and the other relevant information and it is controlled by the university librarian.

In this report there is Gantt chart and Trello board for the assignment planning, use case diagrams, sequence diagrams that will be used as reference to implement the library system.

The figure below is the is the Gantt chart for this assignment’s planning, however it capture the start time and end times of the nine assignments tasks as shown below.

The screenshots represents the Trello Board for this assignment’s planning ,it has various cards that indicate the activities and the due dates as indicated in the above Gantt chart and it show the updating processes as time moves on as shown below (Goyal 2011).

1. Due in next day.

1. Due in the next week.

• Due in the next month.

1. Due date marked complete.

1. Not marked as complete.

The library system is used by the librarian to carry out various operations where he/she add the borrowers, the staff members ,the student members and the library materials that are borrowed by the various borrowers (Singh  2016).

He is also given the privilege of removing the borrowers who left the university and they had cleared all the library charges while making the borrowers with pending charges deactivated.

However the librarian keeps record of the borrowed items and the respective borrowers and in case they exceed the set deadline the librarian charges them some amount of money as a fine.

The below are the requirements documentation for the “pay fine” scenario.

1. System allow librarian to add borrowers.
2. System should set status of borrowers without library card as pending.

• System should calculate fine for any borrower who fails to return the book within the due date.

1. System should prevent borrowers with more than $25 fine charges to borrow books until they pay the amount to librarian.
2. System should enable the librarian receive the payment and mark the borrower’s fine as paid.
3. The system should generate a receipt to be issued to borrowers after paying the fines

The below is the UNI library information system use case diagram indicating the actors who are the people using it and the various operations that are represented by the use cases.

The below are the textual description use cases that describes the various action that the librarian and borrower performs in the process of borrowing the books, the borrower in this case are allowed to borrow books after correcting their library cards which they use to login the library system through the librarian, search for a book and then borrow it if at all it is available.

However the book is put by the librarian or borrowers on hold if they are already on loan and they can borrow it when it is returned to the library.

Below are various use cases textual descriptions for borrowing and returning of the library book items.

Below is the activity diagram for searching and putting a book on hold in the library information system

Below are the various test case generations.

Conclusion

The UNI library system is a very important system that enables the university to keep good record of the library materials and assist the librarian in the issuance and easy retrieval of the materials without much struggle.

However the system had enhanced good service delivery to the book borrowers where they are able to quickly and easily search for the books required using the book name or book IDs and therefore I recommend fully implementation of the system and adoption of the system by other similar institutions for better records keeping.
