Hello! I created the sequence chart below to depict a scenario of interaction between a library patron and the new Thrive University (TU) library system.

Scenario: Book Search and Reservation

Description: Bob, a registered user, searches for a book and reserves it for borrowing.

Explanation:

1. User (Bob): Initiates a search for a specific book using the bibliographical search interface.
2. System: Processes the search query and returns a list of matching books.
3. User (Bob): Selects a book and requests to reserve it.
4. System: Checks the availability and reserves the book for Bob.
5. System: Sends a confirmation message to Bob with details of the reserved book.

Could you help me create a Dataflow Diagram for this scenario? Thank you in advance!
