It is modelling process that used for the data visualization in theprocessing. DFD shows different kind of information that input and output from the system. It isadvanced system that always maintain the entire model and structure of information in propermanner. Data flow diagram is mainly useful in the documentation that explore the high level ofdesign in the terms of data flow (Bing‐hai and Wang, 2015). Data flow diagram is contain the different processes and other two external entities ordata stores. It doesn't require for designing the diagram that governs to choose the correctposition of shapes that implement in the data flow diagram (Hao and Giunchiglia, 2015). Theperformance and maintenance is process that takes for inspection where data store as input andalso provide the customer bill. All the details of stored in the work stores. Data flow Diagram:

2 level DFDAccording to the diagram, it can be concluded that there are two different level ofdiagram that represent in specific manner. In 0 level DFD, Supplier can provide the new productof cycle according to their demand. It is mainly focused on to supply the inventory product to thecustomers. This is the actual data flows in 0 level DFD.In 1 level DFD, customer connect with the shop to repair their bicycle and also connectwith the mechanic.
