UML Diagram for Online Job Portal

Online Job Portal defines the feature and functionalities, where employees can search and apply for the job. In the same application, employers can register and post jobs or openings in their organizations.

In this blog will create Components, Activity, Usecase, and Sequent UML diagrams for online job portal projects.

UML Diagram for Online Job Portal

We’ve compiled structural UML diagrams i.e. component diagrams, and three types of behavioral UML diagrams i.e. Activity, Sequence, and Use Case diagrams for the Online Job Portal. We have also explained the data flow diagram (DFD) for this project.

This project is designed to help students in planning their careers and it will help the students to apply to the job where they fit in. This Project is performing all the crud operations like ADD//UPDATE/DELETE functions.

Component diagram for Online Job Portal

The component diagram below shows the structural relations between components in an Online Job Portal System. The connected components by lines represent relationships within the systems.

Admin will be responsible for maintaining the system and also, keeping a check on the recruiters and management of the system, can add/remove/update recruiters from lists, etc. An Admin is part of the (online job portal in java) who will manage all the requiter and users.

A user(job Seeker) can view the job as a front-end user who can apply for the job and can send a mail to the requiter or company.

Activity diagram for Online Job Portal

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 can Add/Remove/Update recruiter,

A recruiter can View/Confirm/Cancel job applications, manage recruiter/job categories, details, and vacancies can manage applicants, reports, etc.

Admin can add/remove/update recruiters from lists, etc. An Admin is part of that will manage all the requiter and users.

Users can register on this platform and can apply for the Jobs available based on their skills and interest.

Sequence diagram for Online Job Portal

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.

The user can perform login and registration operations. The user can search for a job. The user can view the job and apply for that Job. The user can Edit/Update his profile. The user can search for jobs according to the company.

Whereas, Recruiters can add/Edit/Delete jobs, check the list of users who applied for their job, and can send the interview mail or contact the applicants.

Use Case Diagram for Online Job Portal

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 within the entire process (and where they’re excluded).

As an Admin can add recruiter and users, whereas the recruiter will be able to access add jobs, and view applicants(apply job list). Users (Candidates) can view recruiters and apply for jobs.

DFD Diagram for Online Job Portal

A data flow diagram represents the flow of information for any process or system. It shows the system with its relationship to external entities.

Admin can ADD/VIEW/UPDATE/DELETE Recruiter and User. The recruiter can ADD/VIEW/UPDATE/DELETE Jobs. Admin can VIEW/UPDATE/DELETE Users. A recruiter can VIEW the Jobs applied by users. All Users can change their Password. All Users can VIEW/UPDATE Profiles.

On the other hand, users can view different recruiters and apply for jobs. Users can view jobs applied.
