It contains all of the userflow and their entities such all the flow of Employee, Department, Designation, Leave, Salary, Attendance, Task. All of the below diagrams has been used for the visualization of data processing and structured design of the Employee Management process and working flow.
Zero Level Data flow Diagram(0 Level DFD) of Online Employee Management System :
This is the Zero Level DFD of Online Employee Management System , where we have eloborated the high level process of Employee Management . It’s a basic overview of the whole Online Employee Management System or process being analyzed or modeled. It’s designed to be an at-a-glance view of Salary,Attendance and Task showing the system as a single high-level process, with its relationship to external entities of Employee,Department and Designation. It should be easily understood by a wide audience, including Employee,Designation and Salary In zero leve DFD of Online Employee Management System , we have described the high level flow of the Employee Management system.High Level Entities and proccess flow of Online Employee Management System :
- Managing all the Employee
- Managing all the Department
- Managing all the Designation

- Managing all the Salary
- Managing all the Attendance
- Managing all the Task
First Level Data flow Diagram(1st Level DFD) of Online Employee Management System :
First Level DFD (1st Level) of Online Employee Management 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 Online Employee Management System system as a whole. It also identifies internal data stores of Task, Attendance, Salary, Leave, Designation that must be present in order for the Employee Management system to do its job, and shows the flow of data between the various parts of Employee, Designation, Attendance, Task, Salary 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 Employee Management .Main entities and output of First Level DFD (1st Level DFD):

- Processing Task records and generate report of all Task
Second Level Data flow Diagram(2nd Level DFD) of Online Employee Management System :
DFD Level 2 then goes one step deeper into parts of Level 1 of Employee Management . It may require more functionalities of Employee Management to reach the necessary level of detail about the Employee Management functioning. First Level DFD (1st Level) of Online Employee Management System shows how the system is divided into sub-systems (processes). The 2nd Level DFD contains more details of Task, Attendance, Salary, Leave, Designation, Department, Employee.Low level functionalities of Online Employee Management System
