For the previous problem, use the DCD and identify a set of CRC cards that would be used for the Patient visits dentist use case. Assume that the visit is a simple checkup and that no other procedures will be performed. In other words, entering specific procedures is done with a different use case. You might want to get a set of index cards and actually do a design session. Either scan your cards or type the information to give to your instructor. Once you have identified the responsibilities by class, update the DCD by adding method names to the classes in the DCD.
