Order Processing System Data flow diagram is often used as a preliminary step to create an overview of the Order without going into great detail, which can later be elaborated.it normally consists of overall application dataflow and processes of the Order process. It contains all of the userflow and their entities such all the flow of Product, Customer, Order, Bill, Company, Payment, Receipt. All of the below diagrams has been used for the visualization of data processing and structured design of the Order process and working flow.
Zero Level Data flow Diagram(0 Level DFD) of Order Processing System :
This is the Zero Level DFD of Order Processing System, where we have eloborated the high level process of Order. It’s a basic overview of the whole Order Processing System or process being analyzed or modeled. It’s designed to be an at-a-glance view of Company,Payment and Receipt showing the system as a single high-level process, with its relationship to external entities of Product,Customer and Order. It should be easily understood by a wide audience, including Product,Order and Company In zero leve DFD of Order Processing System, we have described the high level flow of the Order system.High Level Entities and proccess flow of Order Processing System:
- Managing all the Product
- Managing all the Customer
- Managing all the Order
- Managing all the Bill
- Managing all the Company
- Managing all the Payment
- Managing all the Receipt
First Level Data flow Diagram(1st Level DFD) of Order Processing System :
First Level DFD (1st Level) of Order Processing System shows how the system is divided into sub-systems (processes), each of which deals with one or more of the data flows to or from an external agent, and which together provide all of the functionality of the Order Processing System system as a whole. It also identifies internal data stores of Receipt, Payment, Company, Bill, Order that must be present in order for the Order system to do its job, and shows the flow of data between the various parts of Product, Order, Payment, Receipt, Company of the system. DFD Level 1 provides a more detailed breakout of pieces of the 1st level DFD. You will highlight the main functionalities of Order.Main entities and output of First Level DFD (1st Level DFD):
- Processing Product records and generate report of all Product
- Processing Customer records and generate report of all Customer
- Processing Order records and generate report of all Order
- Processing Bill records and generate report of all Bill
- Processing Company records and generate report of all Company
- Processing Payment records and generate report of all Payment
- Processing Receipt records and generate report of all Receipt
Second Level Data flow Diagram(2nd Level DFD) of Order Processing System :
DFD Level 2 then goes one step deeper into parts of Level 1 of Order. It may require more functionalities of Order to reach the necessary level of detail about the Order functioning. First Level DFD (1st Level) of Order Processing System shows how the system is divided into sub-systems (processes). The 2nd Level DFD contains more details of Receipt, Payment, Company, Bill, Order, Customer, Product.Low level functionalities of Order Processing System
