Relational Database Design

The following question is based upon the Patient-Treatment relation which records the details of transactions occurring in a medical surgery. You may assume the data are representative.

You have been asked to design a relational database for this system. You know that there are problems with the current design and that it will need to be modified in order to work effectively.

You need to write a 1-2 page report that addresses the following:
1. What are the specific problems associated with the current design and why do they arise?
2. How would you change the current design and how does your new design address the problems you have identified with the current design.
In order to receive high marks for this question, you will need to demonstrate an understanding of the theories discussed in Topics 1, 2 and 3, how they apply to this problem, and justify the changes you are making to the system. Simply providing the amended design (even if it is correct) will only attract a small percentage of the marks for this question.
