Question

2. Precise Metamodeling with UML and OCL

You are asked to produce a precise domain model for a healthcare clinic, whose requirements are expressed below. Using the USE tool, provide a UML class diagram that captures its basic concepts. Choose appropriate classes (enumeration, abstract or concrete), attributes (with types), associations (with directions, multiplicities, compositions, and names or roles), and required OCL expressions (in text, outside the diagram), but do not be concerned with visibility or operations. Please stick to the description below; do not extrapolate based on prior knowledge of clinics!

1. a) A clinic contains staff members, patients, and prescriptions.

2. b) Staff members and patients both have names.

3. c) A staff member is necessarily an admin, a nurse, or a physician.

4. d) An admin has a duty description.

5. e) Each prescription has a drug type and a positive Defined Daily Dose (DDD).

6. f) Known drug types are: pain, sleep, anxiety and stimulant.

7. g) A prescription is produced either by a physician or by a nurse.

8. h) A prescription always targets one patient, but patients can get multiple prescriptions.

9. i) A nurse is limited to sleep and anxiety drugs for prescriptions.

10. j) To avoid legal confusion, within a clinic, the staff members who can make prescriptions

    must have unique names among themselves.

11. k) A patient must not be prescribed a total DDD higher than 5 for anxiety drugs.

12. l) On average, a doctor cannot prescribe a DDD over 4 of sleep drugs.

You need to give your .use file and .clt (layout) file, and to include the corresponding diagram in your report.
