                Using my Flight Example project, please
                
                Build:
                
        ->      an Entity class to hold the data from the Flights table
                
        ->      a DAO interface with these methods:
                
                        public List<Flight> findFlightByOriginAirport(String originAirport)

                        public List<Flight> findFlightByDestinationAirport(String destinationAirport)

                        public List<Flight> findFlightByOriginCity(String originCity)

                        public List<Flight> findFlightByDestinationCity(String destinationCity)
                
        ->      a DAO Implemention to make this code work
                
        =>      change the Appl to list all flight from Boston/BOS
        
        My SQL:
        
         private static final String FIND_BY_ORIG_AIRPORT = 
                    "Select * from FLIGHTS where ORIG_AIRPORT = ?";
         private static final String FIND_BY_DEST_AIRPORT = 
                    "Select * from FLIGHTS where DEST_AIRPORT = ?";
         private static final String FIND_BY_ORIG_CITY = 
                    "Select * from FLIGHTS F " +
                "  inner join CITIES C " +
                " on F.ORIG_AIRPORT = C.AIRPORT " +
                " where C.CITY_NAME = ?";
         private static final String FIND_BY_DEST_CITY = 
                    "Select * from FLIGHTS F " +
                "  inner join CITIES C " +
                " on F.DEST_AIRPORT = C.AIRPORT " +
                " where C.CITY_NAME = ?";
