Sales and Inventory System DFD Level 0 1 2 | Best Dataflow Diagrams for 2021
Hi there Itsourcecoders! Today I will give you ideas about the Sales and Inventory System DFD Diagram levels 0 1 2 for 2021. This PDF will also give you deep understanding about Sales and Inventory system Data Flow Diagram (DFD) levels 0, 1 and 2. It will teach you in managing sales and Inventory information as well as the flow of activities happens in the system.
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 flows that the System can generate:
- Managing Sales Information
- Managing Customers Info
- Manage Stocks Information
- Manage Payment Records
- Trace Inventories

Time needed: 10 minutes.
Here’s the Dataflow Diagram levels 0 1 2 for Sales and Inventory System and step-by-step way on how to create Sales and Inventory system DFD.
- Sales and Inventory System DFD Level 0
To start with, let us familiarize what is Sales and Inventory system level 0.
The Sales and Inventory 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 Sales and Inventory 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 Sales and Inventory monitoring. This will also serve as a guide as you go through the deeper processes of the Sales and Inventory 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.
- Sales and Inventory System DFD Level 1
Next to the context diagram is the level 1 data flow diagram.
The content of Sales and Inventory 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.
The following are essential data to accommodate:
• Purchasing Records
• Transactions Record
• Supplier Record
These procedures require information such as record of customers, orders, reservations, deliveries and payment from which served as the bases for sellers and admin to manage the sales and inventory system. This type of data is represented by a data store.
With being knowledgeable about the DFD level 1 of the Sales and Inventory 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 Sales and Inventory System.
- DFD for Sales and Inventory System Level 2
After presenting the Sales and Inventory 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 Sales and Inventory 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 Sales and Inventory 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 Sales Information
• Managing Customers Info
• Manage Stocks Information
• Manage Payment Records
• Trace Inventories
DFD level 2 let’s you know the ideas on where does the data inputs goes and inputs comes within the Sales and Inventory System. Considering the the dataflow levels mentioned above, you can determine well the importance 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 and design your own project DFD levels 0, 1 and 2.
Additional Knowledge on DFD Levels 0 1 2 of Sales and Inventory System 2021
What is Sales and Inventory 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 Sales and Inventory 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 Sales and Inventory 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.
