Shopping Cart System Data flow diagram is often used as a preliminary step to create an overview of the Shopping without going into great detail, which can later be elaborated.it normally consists of overall application dataflow and processes of the Shopping process. It contains all of the userflow and their entities such all the flow of Products, Category, Payments, Customer, Cart, Orders, Login. All of the below diagrams has been used for the visualization of data processing and structured design of the Shopping process and working flow.


Zero Level Data flow Diagram(0 Level DFD) of Shopping Cart System :

This is the Zero Level DFD of Shopping Cart System, where we have eloborated the high level process of Shopping. It’s a basic overview of the whole Shopping Cart System or process being analyzed or modeled. It’s designed to be an at-a-glance view of Cart,Orders and Login showing the system as a single high-level process, with its relationship to external entities of Products,Category and Payments.

First Level Data flow Diagram(1st Level DFD) of Shopping Cart System :

First Level DFD (1st Level) of Shopping Cart 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 Shopping Cart System system as a whole. It also identifies internal data stores of Login, Orders, Cart, Customer, Payments that must be present in order for the Shopping system to do its job, and shows the flow of data between the various parts of Products, Payments, Orders, Login, Cart of the system.

Second Level Data flow Diagram(2nd Level DFD) of Shopping Cart System :

DFD Level 2 then goes one step deeper into parts of Level 1 of Shopping. It may require more functionalities of Shopping to reach the necessary level of detail about the Shopping functioning. First Level DFD (1st Level) of Shopping Cart System shows how the system is divided into sub-systems (processes). The 2nd Level DFD contains more details of Login, Orders, Cart, Customer, Payments, Category, Products.
