Online Auction System represents the interactions between Sellers, Bidders, Admin, and Support Staff. Sellers can list items, update listings, and view bids, while Bidders can browse auctions, place bids, make payments, and give feedback. The Admin manages users, approves listings, blocks suspicious accounts, and generates reports. Support Staff respond to user queries and help track bids. This diagram effectively shows how the online auction platform manages real-time bidding, secure transactions, and user management, ensuring a seamless experience for buyers and sellers through systematic digital coordination.
