Item Age Restriction is used to define a minimum age that customer must be to purchase an Item, or that an employee must be in order to sell an Item. Fields: - ItemId - MinimumCustomerAge (null allowed) - MinimumEmployeeAge (null allowed) - F/T/C The Person entity will also be modified to add BirthTime (aka. Date), allowed to be null. Customers wouldn't be prompted for this unless they purchase an item with age restrictions on it. Existing UCs for Customers and Employees would need to be enhanced to support this.
The BirthTime field addition shouldn't be necessary, Birthday now exists on the Profile entity.
