  • E-commerce Website DFD Level 0

    To start with, let us familiarize what is E-commerce Website DFD level 0.

    The E-commerce Website DFD 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 E-commerce Website 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 E-commerce Website monitoring. This will also serve as a guide as you go through the deeper processes of the E-commerce Website 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.

  • E-commerce Website DFD Level 1

    Next to the context diagram is the level 1 data flow diagram.

    The content of E-commerce Website 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:
    • Sales Monitoring Records
    • Payment Records
    • Admin and user Logs
    • Transactions

    In addition to that, this may also serve as your reference on how the inputs or data fed on the website. Then you will be also informed about the outputs that the website gives.

    These processes shown in the DFD were all based on the concept of E-commerce Website.

  • E-commerce Website Level 2

    After presenting the E-commerce Website 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 E-commerce Website.
    • The Level 2 DFD for the website should represent the basic modules as well as data flow between them.
    • Since the DFD level 2 is the highest abstraction level, its E-commerce Website 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 Revenue Information
    • Manage Payment Records
    • Monitor and Manage Products’ Information
    • Manage Transaction Records

    DFD level 2 let’s you know the ideas on where does the data inputs goes and inputs comes within the E-commerce Website. 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 website.

    This DFD will also be your references as you make and design your own project DFD levels 0, 1 and 2.

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.

What does E-commerce Website 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.
