system should include the following processes:

$1.$ Book Management: Add new books, update book information, and remove books from

the catalog.

$2.$ Member Management: Register new members, update member information, and

manage member accounts.

$3.$ Book Lending: Allow members to borrow books, return books, and check the availability

of books.

$4.$ Fine Calculation: Calculate fines for overdue books and process fine payments.

$5.$ Report Generation: Generate reports on book inventory, member activity, and financial

summaries.

Task: Create a data flow diagram $($DFD$)$ for the library management system. The diagram should

include the main processes, data stores, external entities, and data flows.

between them and the data stores
