LITERATURE REVIEW

1. The Shift from Paper-based Systems to Digital Systems

Traditional paper-based systems have long been used for managing academic records, but
they are prone to inefficiencies such as data loss, difficulty in retrieval, and errors in updating
records. Digital systems address these challenges by centralizing data and providing quicker
access, especially when departments need information for accreditation or reporting.
Research by Chien et al. (2018) highlights that digital systems increase operational efficiency,
reduce manual effort, and improve data accuracy. Gonzalez et al. (2019) also emphasize that
these systems help institutions meet the growing demand for real-time access to academic
records.

2. Role-based Access Control and Security

Role-based access control (RBAC) is crucial for protecting sensitive academic data in digital
systems. Ferreira et al. (2017) stress the importance of RBAC in ensuring that only authorized
users can access or modify certain information, thereby reducing the risk of unauthorized
changes. The security of user data is enhanced through encryption techniques like hashing
and salting, as noted by Ravi et al. (2020). Additionally, technologies like JWT (JSON Web
Tokens) and cookies ensure secure authentication and session management, maintaining the
integrity of user data.

3. Web-based Systems in Academic Environments

Web-based systems offer increased accessibility and flexibility, allowing users to interact with
the system across various devices. Lin et al. (2021) highlights that systems like Learning
Management Systems (LMS) and Student Information Systems (SIS) are commonly used to
manage academic and student data. Similarly, the Department Information System (DIS)
employs a web-based architecture using React for a responsive interface, ensuring the system
is usable on both desktops and mobile devices. The flexibility of these systems makes them
highly suitable for academic departments with diverse user needs.

4. Data Management and Error Handling

Managing data in academic departments can be challenging due to large volumes and the risk
of data inconsistency. Agarwal et al. (2017) note that error handling and data validation are
key to ensuring the accuracy and integrity of data in digital systems. The DIS addresses these
issues by incorporating real-time validation during data entry and providing error messages
for incorrect inputs. This reduces the risk of human error and ensures that only valid data is
stored.

5. Benefits of Role-based Data Access and Efficient Reporting

Role-based access and data organization enhance the efficiency of reporting in academic
settings. Ritchie et al. (2019) show that by structuring data into specific sections, like
Department of Computer Science and Engineering, NIT CALICUT 3
publications or projects, academic departments can generate reports quickly and accurately.
This is especially beneficial when departments need to produce reports for accreditation or

single-page applications that can efficiently update and render UI components based on user
interaction and state changes. Below are the key details regarding the frontend
implementation of the DIS project:

3.1 Frontend Implementation

The frontend of the ”Department Information System” platform is built using React.js,
a popular JavaScript library for building dynamic and responsive user interfaces.

3.1.1 Project Structure

• Src/: Contains all source code files, including components, assets, utilities, and
services.

• Components/: Houses the reusable UI components such as buttons, forms,

navigation bars, modals, etc.
• Pages/: Contains the specific pages for different views in the application like the
login page, signup page, home page, and section pages (e.g., publications,
projects).
• Services/: Contains files responsible for handling API requests and managing
authentication tokens.
• Utils/: Helper functions such as data validation, error handling, and form
validation.
• App.js: The main entry point for the application where routes are defined and global states
are managed.
3.1.2 User Interface Components
The application is designed with a user-friendly interface that supports different user
roles (Admin, Staff, and Student). React components were built to ensure a dynamic and
responsive UI:

4
  Reusable Components: Common components such as buttons, modals, and input
fields are created as reusable components. These components can be easily
included across multiple pages, ensuring consistency in the design.
 Navigation Bar: A dynamic navigation bar is implemented, which changes based
on the user’s role (Admin, Staff, or Student). It displays relevant menu items and
sections based on the user’s permissions. The navigation bar is fixed at the top and
is easily accessible for users to navigate through the app.
 Responsive Design: Using CSS Flexbox and Media Queries, the layout adapts to
different screen sizes, ensuring a seamless user experience on desktops, tablets,
and mobile devices. This responsive design is implemented in all pages and
components, including forms, tables, and lists.

3.1.3 Routing and Navigation

The frontend uses React Router for handling navigation between pages. React Router allows
for dynamic, client-side routing that doesn’t require full page reloads, offering a smooth user
experience. Here’s how routing is implemented:

 Private and Protected Routes: Certain pages (such as the dashboard, user profile, and
sections like publications and projects) are protected and can only be accessed by
authenticated users. This is achieved using React Router’s <PrivateRoute />
component, which checks for a valid authentication token (JWT) before allowing access
to a page.
 Role-Based Routing: After login, users are redirected to a role-specific dashboard
based on their authentication. Admin users are directed to an admin dashboard, staff to
a staff dashboard, and students to a student dashboard. This role-based routing ensures
that users can only see and interact with sections they have access to.
