Consider an airline reservation database system in which travel agents are allowed online access to make reservations on any flight. Is it possible for two travel agents located in different cities to book their respective clients the last seat on the same flight? Explain your answer. 2. What problems are caused by data redundancies? Can data redundancies be completely eliminated when the database approach is used? Why or why not? 3.
