It contains all of the userflow and their entities such all the flow of Mailbox name, Domain name, Userdata, Subject, Message data, Mailserver Address, Login. All of the below diagrams has been used for the visualization of data processing and structured design of the Mailing process and working flow.
Zero Level Data flow Diagram(0 Level DFD) of Mailing System :
This is the Zero Level DFD of Mailing System, where we have eloborated the high level process of Mailing . It’s a basic overview of the whole Mailing System or process being analyzed or modeled. It’s designed to be an at-a-glance view of Message data,Mailserver Address and Login showing the system as a single high-level process, with its relationship to external entities of Mailbox name,Domain name and Userdata.

- Managing all the Mailbox name
- Managing all the Domain name
- Managing all the Userdata

- Managing all the Message data
- Managing all the Mailserver Address
- Managing all the Login
First Level Data flow Diagram(1st Level DFD) of Mailing System :
First Level DFD (1st Level) of Mailing 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 Mailing System system as a whole.

- Processing Message data records and generate report of all Message data
- Processing Mailserver Address records and generate report of all Mailserver Address
- Processing Login records and generate report of all Login
Second Level Data flow Diagram(2nd Level DFD) of Mailing System :
DFD Level 2 then goes one step deeper into parts of Level 1 of Mailing . It may require more functionalities of Mailing to reach the necessary level of detail about the Mailing functioning. First Level DFD (1st Level) of Mailing System shows how the system is divided into sub-systems (processes). The 2nd Level DFD contains more details of Login, Mailserver Address, Message data, Subject, Userdata, Domain name, Mailbox name.Low level functionalities of Mailing System
