Introduction - Key Functionalities of an LMS in Python
A library management system or LMS is a program that manages information around borrowing, issues, and members. In this study, various scopes around an effective LMS implementation have been presented. This study's main aim is to explore LMS's storage method. Five major tasks have been completed to fulfill the scope. Task 1 deals with code that allows a member to borrow books. Task 2 deals with a code that allows members to return the book. In task 3, functionality has been provided that allows a member to apply for membership. Task 4 presents functionality that allows a member to return a book. Finally, task 5 illustrated on implementation of a notification system.

The code provided in this section illustrates that this will be helping the members to borrow a book in the system. Implementation of this code should be allowing the members to borrow a book and automatically record the results as a new book loan (Jamwal, and Singh, 2019). One of the specific aspects of this function is that it considers cards as attributes of the members.
Thus, it can be said that, through the help of this functionality, borrowing books from the system along with recording the activity should become significantly easy.
Member Classes with a method scan ()
Figure 2: Dummy data to test the code
The precondition for this operation is that the Book and Member classes must have a method scan () which will return the id of an instance of each respectively. The post condition is that a new book loan record will be created with the id of Member and the id of the book.
Testing the code using dummy data
For testing this code, dummy data can be used to create instances of the Book and Member classes and the scan () method can be used to obtain their ids. The scanned ids can then be used to create a new bookloan record.
Task 2
Return a book
Here, the code provided in this section is suggesting that this should be helping a member to return a book. This function is significantly similar to the issue () function. The code provided can be seen can directly help in terms of allowing members to return a book as well as storing the data on the activity (Kumar, and Prasad, 2021).
def return_book (member) allows a member to return a book, ensuring that necessary data is stored. The main post conditions can be executed as that the member ID, and which book the member wants to return. The functions can help to give the status of returned book and it can allow the members to return the book in time (Nelson, and Prescott, 2019).
The members can now efficiently borrow a book and return it without facing much complexity in the system. The new functionality can have a direct effect on the member's ease of use and the system's usability.
Test the functionality
For the test the functionality of the program with dummy data, a set of dummy data is used and provides as input into the program. This data is designed to test the different scenarios so that the program should able to handle. Then the program’s output is observed and compare it to the desired result. If the output matches the desired result, then the program is working correctly. If it does not, then further debugging and testing is needed.
Task 3
Apply for membership
In this section, a code has been presented that can help in terms of improving ease of use in membership applications. It can be seen that the code should be directly helping the members to apply for membership in the system. Moreover, it should be also mentioned that storage of information on the membership request as well as approval will be done (Chukwu and Nneka, 2021).
Figure 4: Allow members to apply for membership
This can help to execute the storage of the main information’s regarding to the membership’s request. Every day the list can be evaluated with proper entries and it has been evaluated using python codes. The above figure can show the executed and developed member’s names, address of the members, phone number, membership id, date of the application and the membership card number. The library must store the details of the new members until their cards arrive (Bingol, and Krishnamurthy, 2019). Upon receipt of the cards, the members can then be added to the library's database and issued with their membership cards. To ensure the security of the data, the library should have appropriate data protection measures in place. Additionally, the library should ensure that any external print companies they use are also compliant with data protection regulations. Thus, this functionality can have a direct improvement in the efficiency of the system while storing data around membership requests.
Task 4
Reserve a book
Reserving a book feature is also a critical part of a design and implementation technique using python codes and classes with creating some JSON files. Thus, this code provided can provide help in terms of reserving a book.
Figure 5: Allow members to reserve a book
A JSON file has been created named “reservedbooks” and it can be executed as the functionality of which book is already reserved. Store book availability data in JSON format for long-term use. The storage has been permanently kept in store and it can be stored before a book get available. Here the figure above can show the reserved book list and the program can show which book is reserved with the book title and book number and proper status as available and reserved.
The members can directly reserve a book in case there is enough availability. This functionality helps members to reserve a book through the system and the appropriate record gets stored regarding that (Hess et al. 2020). Therefore, it can be said that this functionality needs to be considered an essential aspect of the system that allows members to instantly reserve a book through the system.
Task 5
Implement a notification system
In the final task, functionality on a new notification system that allows for better notification visibility has been provided. It can be seen that through the help of this program, the implementation of a notification system that can communicate the ongoing activities of a member has been done (Mohammed et al. 2019).
Using design patterns to create a notification system, the program would need to incorporate Observer, Factory and Strategy patterns. The Observer pattern would allow the program to subscribe multiple observers to the notification system, while the Factory pattern would be used to create the notification objects.
Figure 6: Allow members to reserve a book
The Strategy pattern would be used to define the logic for sending different types of notifications. The program could include a Notification class with a send () method, which could be used to send notifications. This method could use the Factory pattern to create an appropriate notification object and the Strategy pattern to determine the logic for sending the notification.
Test using sendEmail() method
Figure 7: Allow members to reserve a book
The Observer pattern would be essential for the notification system to allow multiple observers to subscribe to the system. This would allow the program to send notifications to multiple observers, such as email addresses or other contact information (Vyshnavi et al. 2019).
Finally, the send Email () method could be used to send the notifications by email, printing the message to the console. This new notification system should be allowing features like a notification when a membership card gets available for a new member or notification for card collection and many more. Thus, these new design features can have a direct impact on the ease of use of the system. Henceforth, it is evident that this new feature can have a direct effect on the new LMS’s usability.
Conclusion
Therefore, it can be said that the new system allows a member to the request of borrowing a book. Similarly, the new LMS also helps a member effortlessly return a book that was taken from the library. On the other hand, this new LMS also helps in terms of helping a member towards seamless request posting for a new membership. Moreover, the new functionality allows a member to reserve a book when it is available in the library. Finally, the new notification system that can be seen as the prime feature of this new redesigning of this LMS can have a direct impact on the communication between the members and library management. Thus, through the help of this functionality, an efficient, as well as effective new LMS, can be implemented. It is evident that the new system is capable of coping with more data and sound system management within these added functionalities.
