Lucrezia Lauri enhanced the data access layer for the Lollolewa/EsempiCorso repository by implementing robust ticket retrieval features and establishing a scalable ORM foundation. She introduced new methods in the TicketDao to support querying tickets by code pattern and airport ID, leveraging Java and SQL to streamline data access. Using the DAO pattern with Hibernate and JPA, Lucrezia configured ORM mappings for Airport, Passenger, and Ticket entities, initializing EntityManager components to enable efficient database interactions. Her work focused on maintainability and future analytics, laying groundwork that reduces inspection time and supports extensible reporting without introducing new bugs during the development period.
