All of the below diagrams has been used for the visualization of data processing and structured design of the Inventory process and working flow.
Zero Level Data flow Diagram(0 Level DFD) of Inventory System :
This is the Zero Level DFD of Inventory System, where we have eloborated the high level process of Inventory. It’s a basic overview of the whole Inventory System or process being analyzed or modeled. It’s designed to be an at-a-glance view of Expiry,Manager and Login showing the system as a single high-level process, with its relationship to external entities of Goods,Category and Worker. It should be easily understood by a wide audience, including Goods,Worker and Expiry In zero leve DFD of Inventory System, we have described the high level flow of the Inventory system.High Level Entities and proccess flow of Inventory System:

- Managing all the Worker
- Managing all the Warning
- Managing all the Expiry
- Managing all the Manager

First Level Data flow Diagram(1st Level DFD) of Inventory System :
First Level DFD (1st Level) of Inventory 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 Inventory System system as a whole. It also identifies internal data stores of Login, Manager, Expiry, Warning, Worker that must be present in order for the Inventory system to do its job, and shows the flow of data between the various parts of Goods, Worker, Manager, Login, Expiry of the system.

DFD Level 2 then goes one step deeper into parts of Level 1 of Inventory. It may require more functionalities of Inventory to reach the necessary level of detail about the Inventory functioning. First Level DFD (1st Level) of Inventory System shows how the system is divided into sub-systems (processes). The 2nd Level DFD contains more details of Login, Manager, Expiry, Warning, Worker, Category, Goods.Low level functionalities of Inventory System
