UML Diagram for Employee Payroll Management System

UML diagrams for the Employee Payroll Management project. Following are the different UML diagrams like Components, Activity, Use Case, and Sequence diagrams of the employee payroll management system.

UML Diagram for Employee Payroll Management System

We’ve compiled structural UML diagrams i.e. component diagrams, and three types of behavioural UML diagrams i.e. Activity, Sequence, and Use Case diagrams for the Employee Payroll Management Project. We have also explained the data flow diagram (DFD) for this project.

The main objective of the employee management system project is to manage the employee of any organization and it covers all the basic scope of a Payroll Management System. Managing attendance and Salary of the employee and monitoring the daily work task.

Component diagram for Employee Payroll Management Project

The component diagram below shows the structural relations between components in an Employee Payroll Management system. The connected components by lines represent relationships within the systems. In the diagram, it can be seen that there are components namely product, order, customer, and account.

It shows how the customer component connects to the other components while using the system. Everything from the account details to product booking to payment flow can be seen in the component diagram.

Admin is the primary user. Admin can Add/Remove/Update any details related to the employees into the sytem, maintain employee database, generate salary & invoices for the users, and View/Confirm/Cancel leave requests by Users, etc. Admin can add salary and timesheets for users.

Activity diagram for Employee Payroll Management Project

Activity diagrams in UML display the functionalities of various activities and flow in management processes and software systems. The flow in the activity diagram can be sequential, branched, or concurrent.

Admin will be responsible for maintaining the system and also, keeping a check on users, salary, timesheets, attendance, leave, generating salaries for users, etc. On the other hand, Users can register, log in using the login credentials, and check attendance, update their details. Users can reset passwords. Users can view their salary, timesheets, and attendance. Users can add leave.

Sequence diagram for Employee Payroll Management Project

Sequence diagrams in UML are used to illustrate the sequence of messages between objects in an interaction. A sequence diagram consists of a group of objects that are represented by lifelines and the messages that they exchange overtime during the interaction.

Users can register on the portal using their name, address, and other valid details, view their salary, view timesheets & attendance, etc. After logging in, users can find detailed information about the salaries & timesheets. Users can add and view leaves.

Use Case Diagram for Employee Payroll Management Project

A UML use case diagram can create a broad, high-level view of the relationship between use cases, actors involved, and systems being performed.

As you can see from the examples below, use cases are represented by oval shapes, and the lines then show at which point an actor/user participates and interacts with their corresponding use case. You can see where each actor is involved in the entire process.

For example, Admin will be able to add attendance, leaves, salary, timesheets, and other details into the system. Whereas, users can access the salary use case for viewing salary. Users can add leave, attendance, and profile details.

DFD Diagram for Employee Payroll Management Project

A data flow diagram represents the flow of information for any process or system. It shows the system with its relationship to external entities. Here, we can see how a system’s users and process flow work.

Admin can manage employees, compile & maintain database, generate salary & invoices for the user, manage Existing Users, View/Confirm/Cancel leave requests, manage salary & payments, etc.

Users can Manage “My profile” and add/view leaves & attendance. Users can see salaries and timesheets. Users can change passwords.
