Draw (DFD) Data flow diagram

Answer

Based on the scenario provided, here's a step-by-step guide on how to create a data flow diagram (DFD) for the Medical Center of DeVry:

Step 1: Identify External Entities External entities are the sources and destinations of information entering and leaving the system. In this case, the external entities could be the Patient, Physician, Scheduling Clerk, Registration Clerk, Radiology Technician, and Radiologist.

Step 2: Identify Processes Processes are the activities or functions that transform the data from one form to another. In this scenario, the processes could be "Schedule Examination", "Check-in Patient", "Perform Examination", and "Evaluate Examination".

Step 3: Identify Data Stores Data stores are repositories of data in the system. In this scenario, the data stores could be "Patient File", "Radiology Schedule File", and "Encounter Database".

Step 4: Identify Data Flows Data flows are the routes that data takes between external entities, processes, and data stores. In this scenario, the data flows could be "Demographic and Insurance Information", "Test and Diagnosis Information", "Appointment Date and Time", "Check-in Confirmation", "Examination Data", and "Examination Report and Diagnosis".

Step 5: Draw the DFD Using a software like Microsoft Visio, start by placing the external entities around the edges of the diagram. Then, place the processes in the middle of the diagram. Connect the entities and processes with arrows representing the data flows. Finally, represent the data stores as two parallel lines and connect them to the relevant processes with arrows.

Remember, arrows should be labeled with the name of the data that is flowing, and each process should have at least one data flow in and one data flow out. The direction of the arrow indicates the direction of the data flow.

Step 6: Review and Refine the DFD Review the DFD to ensure that it accurately represents the scenario. Make any necessary adjustments to improve clarity or accuracy.

Step 7: Submit Your Lab Once you're satisfied with your DFD, submit it according to your instructor's guidelines.

Please note that this is a general guide and the specifics may vary depending on the exact requirements of your assignment and the features of the software you're using.

Week 4: Data Flow Diagram

Lab 2 (Week 4): Data Flow Diagram for Medical Center of DeVry

Lab Overview

Scenario/Summary

When a physician within the Medical Center of DeVry orders an outpatient radiology examination, the patient is asked to pre-schedule the examination at the hospital. The patient phones the scheduling department and provides demographic and insurance information, the name of the test to be performed, and the provisional diagnosis from the order sheet the physician has provided. The scheduling clerk inputs this information into the patient file and assigns a date and time for the procedure from the radiology schedule file.

When the patient arrives for the radiology appointment, the registration clerk checks the patient and schedule files, and checks in the patient. The schedule file is updated and an encounter record is created for the patient and filed in the encounter database. Once the patient has undergone the examination, the radiology technician updates the schedule and encounter database. When the radiologist evaluates the examination data, the encounter database is updated with the examination report and diagnosis.

You may a software other than Microsoft Visio, however, it  must be pre-approved by your instructor.

Deliverables

You will construct a data flow diagram that documents the external entities, processes, data stores, and data flows for the above scenario. Once you have completed the diagram, submit it.

Lab Steps

STEP 1: Create a Data Flow Diagram (10 points)

Create a data flow diagram, including external entities.

· On the File menu, point to New, point to Software and Database, and then click Data Flow Diagram.

· From Data Flow Diagram Shapes, drag an External interact or shape onto the drawing page to represent each external source or destination for data.

· Drag more shapes onto the page to represent the processes, states, or entities involved in the data flow you are documenting.

· Indicate the flow of data in your diagram with Center to center shapes and indicate data loops using Loop on center shapes.

STEP 2: Create Data Stores and Processes (20 points)

Create all the components of data stores and processes.

· From Data Flow Diagram Shapes, drag a Center to center shape onto the drawing page. Place it near the two shapes between which you want to show the flow of data.

· To change the direction of the arrow, right click on the shape and adjust the arrows options in the pop-up menu.

· Drag the endpoints of the Center to center shape   to the connection points x at the center of each of the other shapes. The endpoints turn red to indicate that the shapes are connected.

· To change the arrow curvature, drag the selection handle  . To change the location of the ends of the arrows, drag a control handle  .

STEP 3: Create Data Flows (20 points)

Add all the components of data flows based on the scenario.
