UML Diagram for Online Voting System

UML diagrams for Online Voting Project, following are different UML diagrams explaining Components, Activity, Use Case, and Sequence diagrams of the Online Voting System.

The Online Voting application will help to manage the shop, customers, products, and bookings. It allows the shop owner to manage the day-to-day process of a Farming shop conveniently.

UML Diagram for Online Voting System

We’ve compiled structural UML diagrams i.e. component diagrams, and three types of behavioural UML diagrams i.e. Activity, Sequence, Component, and Use Case diagrams for the Online Voting Project.

An online voting system project is designed to automate the voting system. where users can vote for a particular party from a list of multiple parties that can be involved in the election. The complete voting management project including admin and user side is available with source code, project report, and configuration on your machine. Admin, who will manage the overall application; another is the user or customers who can vote.

Component Diagram for Online Voting Project

The component diagram below shows the structural relations between components in an Online Voting 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.

Users or voters can Register into the application and maintain their profile. where the admin can only log in and manage the other users. This is the user module where voters can see the listed elections and parties as per the election so they can vote which is analyzed by the admin user.

Activity diagram for Online Voting Project

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

Admin can add, edit, delete and view the voters and parties. also, the admin can view the elections list and can manage their own profile.

Admin will view the complete voting list and find the winner that is just manual verification because the application is using an internal algorithm to find the winner of the election.

Voters can register into the application and login into the application, After login users can view the parties and vote for their candidate and also voters can view the live winner as election results.

Sequence diagram for Online Voting Project

Sequence diagrams in UML are used to better understand how tasks within a project will function, overlap, and move between objects or components. Sequence diagrams display step-by-step interactions between objects and the order in which those interactions occur.

Users can register into the application and login into the application, After login users can view the parties and vote for their candidate and also voters can view the live winner as an election result. Users will have to enter their voter id number in order to vote for any party.

Use Case Diagram for Online Voting 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.

As from the diagram it can be seen that Admin will be responsible for adding parties.  Whereas, users can vote for any particular party of their choice. Users can select a single party and vote for the same by entering their voter id number. Users can also access the result use case.

DFD Diagram for Online Voting Project

A DFD maps out the flow of information for any process or system. It gives a basic overview of the whole system or process being analyzed. It shows the system with its relationship to external entities. Here, we can see how a system’s users and process flow work.

Initially, Admin and User must be logged in to the system. Upon logging in, both Admin and Customer will land on the home page where they can view results, check list of parties, vote, etc. Admin manages the voting history and parties. Admin will be responsible to Add/Removing/Update any information regarding elections. Admin can update the election results. Admin can manage all the registered Voters and their Voter id details.
