State Machine Diagram for Library Management

About this state machine diagram for library management system

Following is a state machine 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 interactions required for issuance of a book to a registered member

In the following diagram, various states include: check rental history, issue book, update book status, ask to return book, ask to pay dues, update history, and update rental status.

Here in the library management system, upon the arrival of a user, the librarian checks for the user membership. If a member, the librarian looks into the rental history of the member.

Here if an issue is found in either unpaid dues or the user has reached the limit of the maximum borrowed books the librarian asks the member to pay the dues or to return the borrowed books respectively to avail a new request for the book.

If the member resolves the issues by either paying the dues or returning the borrowed books, the librarian proceeds to issue the book to the member, if not the librarian does not accept the request for a book from the member.

If no issue is found in the user history, the librarian issues the asked book to the member. The rental history of the member is then updated inside the management system highlighting the issue of the book, its name, and details. Also, the librarian updates the status of the book from available to unavailable inside the management system.
