About this communication diagram for library management system

Following is a communication diagram for the library management system. Through visual representation with the help of a diagram, it illustrates how different components interact with one another inside the management system. Mainly, it shows the interaction of the librarian with other components for the issue of books to members.

In the following communication diagram, the main objects include the librarian, membership, user history, transaction, and the book inventory system.

The librarian is responsible for the overall management of the library, interaction with the user, and the issuance of the book to the members. The membership of a member is validated using the membership object, which looks into whether or not the individual is a registered member of the library.

The user’s previous history as well as their dues status can be validated using the user history object, which looks into the previous history of the user. The book inventory system is responsible for storing the records of the physical resources present within the library.

Lastly, the issuance of a book is treated as a single transaction, and it's stored. Inside the library management system, the librarian first looks into the inventory system to check whether the book is present or not. If present, the librarian validates the membership of the user.

Upon successful validation, the librarian looks into the previous history of the user to check if the user’s book limit has been reached. If okay, the librarian issues the book, updates the status in the library inventory system, and also updates the user’s history.

All of the above objects interact with one another to achieve the book issuance functionality inside the library management system.
