$($Draw a diagram ON PAPER$)$ and write the corresponding formal written description for the following $($very small$)$

database: An airline asked you to model a dedicated database that is going to keep track of passengers

and their luggage; this database will be used to handle transportation and recovery of lost bags. Each

passenger has a frequent flyer id number $($that identifies them$)$ a name and an address where the bags

may be mailed $($there may be several addresses listed in passenger's profile$).$ Bags, of course, do not

have a unique identifier but they do get numbered at check$-$in time to distinguish between different bags

for any particular passenger. Thus the bag# identifier is guaranteed to be unique per passenger. For each

bag we keep track of its color $($possibly several colors listed$),$ material and size. Bag size is always

specified, while material information does not have to be specified.
