Online Chat Application Dataflow Diagram

Online Chat Application Data flow diagram is often used as a preliminary step to create an overview of the Chat Application without going into great detail, which can later be elaborated.it normally consists of overall application dataflow and processes of the Chat Application process. It contains all of the userflow and their entities such all the flow of Chat, Chat History, Chat Profile, Smiley Chat, Chat User, Chat Group, Chat Delete. All of the below diagrams has been used for the visualization of data processing and structured design of the Chat Application process and working flow.

Zero Level Data flow Diagram(0 Level DFD) of Online Chat Application :

This is the Zero Level DFD of Online Chat Application, where we have eloborated the high level process of Chat Application. It’s a basic overview of the whole Online Chat Application or process being analyzed or modeled. It’s designed to be an at-a-glance view of Chat User,Chat Group and Chat Delete showing the system as a single high-level process, with its relationship to external entities of Chat,Chat History and Chat Profile. It should be easily understood by a wide audience, including Chat,Chat Profile and Chat User In zero leve DFD of Online Chat Application, we have described the high level flow of the Chat Application system.

High Level Entities and proccess flow of Online Chat Application:

• Managing all the Chat
