Pharmacy Management System DFD | Dataflow Diagrams Level 0, 1 and 2
Pharmacy Management System DFD – is created or should be created to determine the flow of data inside a system. This Pharmacy Management System will guide the programmer regarding with what to do and handle in building the system. To give you more ideas about this Pharmacy Management System DFD Level 0, 1 and 2 Topic, there’s essential discussion provided here for you to study.
Here’s what you need to know.
In the DFD, input, processing, and output are used to represent and define the overall system.
The following are the Modules that the Pharmacy Management System Generate:
- Managing Customer
- Managing Drugs Information
- Managing Sales and Stocks
- Generating Reports
Pharmacy Management System DFD Level 0, 1 and 2
Time needed: 10 minutes.
Here’s the Examples of Dataflow Diagram (DFD) level 0, 1 and 2 and step-by-step way on how to create Pharmacy Management System.
- Example Data Flow Diagram for Pharmacy Management System Level 0
To start with, let us familiarize what is Pharmacy management system level 0.
The pharmacy management system level 0 is also known as context diagram. It’s supposed to be an abstract view, with the mechanism represented as a single process with external parties.
This DFD for the system depicts the overall structure as a single bubble. It comes with incoming/outgoing indicators showing input and output data.
In this data flow diagram you will see the general process done in Pharmacy management. This will also serve as a guide as you go through the deeper processes of the Pharmacy management system data flow diagrams.
As you see, when you build the levels of data flow diagrams, the connections of the transactions and data also broadens and gets more specific.
- Example Data Flow Diagram for Pharmacy Management System Level 1
Next to the context diagram is the level 1 data flow diagram.
The content of Pharmacy management system DFD level 1 must be single process node from the context diagram and is broken down into sub processes
In this level, the system must display or reveal further processing information. And the actors that are going to use this system is were the customers, and the pharmacy admin.
The following are essential data to accommodate:
• Customer Information
• Drugs Information
• Stock Records
These procedures require information such as a list of customers, medicines/drugs, sales or purchases, and Stocks from which served as the bases for admin to manage pharmacy transactions. This type of data is represented by a data store.
With being knowledgeable about the DFD level 1 of the Pharmacy Management System, you will know then its broaden context terms.
In addition to that, this may also serve as your reference on how the inputs or data fed on the system. Then you will be also informed about the outputs that the system gives.
These processes shown in the DFD were all based on the concept of Pharmacy Management System.
- Example Data Flow Diagram for Pharmacy Management System Level 2
After presenting the Pharmacy management system DFD levels 0 and 1, next to that is level 2.
Here’s what you need to consider in creating data flow diagram level 2 for Pharmacy management system.
• The Level 2 DFD for the system should represent the basic modules as well as data flow between them.
• Since the DFD level 2 is the highest abstraction level, its Pharmacy management system processes must be detailed that is based on the DFD level 1.
Finally, after figuring the processes given in the system, the user will now have their request being processed.
The Processes that the system should prioritize are as follows:
• Managing Customers
• Managing Medicinal Drugs
• Managing Sales and Revenue
• Stocks Monitoring
DFD level 2 let’s you know the ideas on where does the data inputs goes and inputs comes within the Pharmacy management system. Considering the the dataflow levels mentioned above, you can determine well the work of breaking the processes into more specific manner.
The presented level not only shows you the detailed processes of system, but also gives you precise destination of the data that flows in the system.
This DFD will also be your references as you make your own management system DFD levels 0, 1 and 2.
Additional Knowledge on DFD Levels 0, 1 and 2 of Pharmacy Management System
What is Pharmacy Management System DFD level 0?
A context diagram is another name for it. With the mechanism represented as a single process and external parties it will be an abstract view. It depicts the overall structure as a single bubble with incoming/outgoing indicators showing input and output data.
The data flow diagram level 0 also considers the entire system to be a single process and emphasizes the system’s interaction with external entities.
Context diagrams (level 0 DFDs) are diagrams in which the entire system is represented as a single process.
A single process node and its connections to external entities are depicted in Level 0 data flow diagrams.
What does a Pharmacy Management System level 1 DFD entail?
Level 1 DFDs provide a broad overview but go into greater depth than a context diagram. The single process node from the context diagram is broken down into sub processes in a level 1 data flow diagram.
The System level 1 DFD lists all of the major sub-processes that make up the entire system. A level 1 DFD can be thought of as a “detonated view” of the context diagram.
A single production node and its relationships to external entities are depicted in Level 0 data flow diagrams. Level 1 DFDs provide a broad overview but go into greater depth than a context diagram.
The single process node from the context diagram is broken down into sub processes in a level 1 data flow diagram.
What does a Pharmacy Management System level 2 DFD entail?
The 2-level DFD delves even deeper into the concepts of 1-level DFD. It can be used to plan or record all of the specific/necessary information about how the system works.
Level 2 DFD is the DFD’s highest abstraction level and represents the system’s basic modules as well as data flow between them.
So that completes our discussion fellas! And I hope that this PDF discussion about Data Flow Diagram for Pharmacy Management System | DFD levels 0, 1 and 2 will help you a lot.
