Question

Create the DFD fragments and the Level 0 DFD utilizing Microsoft Visio. Before you begin to work on this activity, review the Microsoft Project and Microsoft Visio page tutorials. These tutorials will help you understand how to create the DFD fragments and the Level 0 DFD. Refer to the DFD fragment and the Level 0 DFD examples in the textbook.

To create the DFD fragments and the Level 0 DFD, utilize the Data Flow Model Diagram template located in the Software category in the Visio 2016 application Home page.

Be sure to select the DATA FLOW MODEL DIAGRAM template and NOT the Data Flow Diagram template.

Your DFDs must address the following requirements:

Submit TWO DFD fragments on PAGE ONE in the Microsoft Visio diagram.

Submit the Level 0 DFD on PAGE TWO in the Microsoft Visio diagram.

Submit the following data in EACH of your two DFD fragments:

1 Process (Process names are verb-related).

2 External Entities (External Entity names are noun-related).

2 input data flows and 3 output data flows per Process (Data Flow names are noun-related).

1 Data Store per Process (Data Store names are noun-related).

1 input data flow and 1 output data flow per Data Store.

Submit the following data in your Level 0 Data Flow Diagram (DFD):

2 Processes.

4 External Entities.

4 input data flows and 3 output data flows per Process.

1 Data Store per Process

1 input data flow and 1 output data flow per Data Store.

Utilize Gane and Sarson symbols. Submit your DFDs in VSDX file format.

The Context Diagram that you created in Module 5 presented the process of how the inventory management system interacts with External Entities. In this assignment, you will utilize data from the same two Casual Format Use Cases that you created in Module 4 to create two detailed Data Flow Diagram (DFD) fragments.

After creating the two DFD fragments, you will integrate the two DFD fragments to create a Level 0 Data Flow Diagram (DFD).

Your task here is to utilize Microsoft Visio^® in a modeling process that transforms the data that was derived in the two Use Cases into the two Data Flow Diagram (DFD) fragments which will then be integrated into the Level 0 DFD.

Answer 1

DFD Level 0 Diagram on MICROSOFT Visio:-

Zero Level Data flow Diagram(0 Level DFD):- It's designed to be an at-a-glance view of Payment, Supplier and Login showing the system as a single high-level process, with its relationship to external entities of Inventory, Customer, and Purchasing.
