RECENT ASSIGNMENT

Question 1 Using the following case study, draw context level and level 0 diagrams showing the logical information flow through the system:
-
A patient request an appointment, and they are offered open appointments from the schedule. The day prior to their appointment, they receive a reminder call, generated from the Daily Call list, and if they have a mobile a text message on the morning of their appointment.

Question 2
Using the following case study, draw context level and level 0 diagrams showing the logical information flow through the system:
-
A patient comes to the hospital and is admitted for a hip replacement. Their treatment is guided by the hip replacement protocol. Many times per day, the caregivers for the patient keep track of what of how the patient is progressing. The physician reviews patient progress and revises the treatment plan, in accordance with the suggestions made by the protocol.

The direct caregivers are also given revised care instructions according to the treatment plan revisions. As more and more patients are seen, the protocol itself get revised, by physicians,. This protocol revisions are stored in the protocol management system.
Question 3

QUESTION 4
Using the following case study, draw ER diagrams showing data stored in the system:
-
An expert system for decoding radiology images has been introduced at the hospital. The patient has radiology images taken, and the image is stored. The clinician then identifies manually the areas of the image that are of interest, and stores this information. Interesting image features are stored, indexed, and compared with other images that exist in the knowledge base. A similarity value is computed for all existing images, and these similar images are returned to the radiology clinician. The clinician uses this information to make a diagnosis. This diagnosis is then stored in the database, further improving the future diagnosis, building on the information that the has been generated by the clinician
