Design the system for a ticket selling web application.

Focus on the architecture and components of the ticket selling web application. Start by outlining the key features such as user authentication, event listings, ticket selection, payment processing, and order confirmation. Consider scalability and performance—how will the system handle high traffic during peak sales? Discuss the database design for storing events and user data, and think about how to implement real-time updates for ticket availability. Lastly, address security measures to protect user data and transactions, and consider how you would approach integrating third-party payment gateways.
