  • DFD for Online Shopping System Level 1

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

    The content of Online Shopping 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 were the customers, seller and online shopping administrator.
    The following are essential data to accommodate:

    • Since the DFD level 2 is the highest abstraction level, its processes must be detailed that is based on the Online Shopping 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 Purchasing Information

    Data Flow Diagram level 2 let’s you know the ideas on where does the data inputs goes and inputs comes within the Online Shopping. 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.

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 is Online Shopping System level 2 DFD Diagram?

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.
