engine
- only contains MANAGERS, READERS, or WRITERS that do some sort of logical work
- does all logic handling and database management
- handles all input verification
database.info
- classes in this package are PURELY for holding INFORMATION
- Guest, Inventory, Reservation, Room etc.
- These will all work very closely with the engine
- Often will be created by GUI and then handled by ENGINE
all GUI packages
- PURELY FOT DISPLAY PURPOSES
- all information passed in will IMMEDIATELY be passed to INFO classes
