8. ''A system is needed to maintain an inventory of the contents of a warehouse. Items
are delivered for storage at any time during the day and must be allocated space. An
identification tag must be attached to every item before storage and a few items need to be
stored in a refrigerated unit. An item can be stored for any period of time but a few items
have an expiry date by which they must be removed from the warehouse.

When items are removed they need to be labelled, packaged for delivery and put on the
delivery truck. The truck driver should be provided a list of delivery addresses for the items.

The system should be able to generate reports showing the current contents of the warehouse
and the last day's deliveries and collections.''

(a) Taking an object-oriented point of view, draw up a list of potential classes, attributes
and external entities using the specification above as a guide. [Marks 5]

(b) Starting with the classes you have identified in part [I], generate a class diagram for
the warehouse software system. Make sure every class is labelled with any key attributes
or operations. [Marks 5]
