Question 6:

Ibid is an e-auction house that auctions refurbished products. Each product has a minimum bid price. Buyers can query the system for a list of products and then select a product to bid on. They can then place a higher bid on the selected product. Transactional Integrity is very important as dirty reads, non-repeatable reads and phantom reads can lead to data inconsistency. What technology combination might be most suitable for addressing Ibid's needs?
