I'm a beginner in app development and am excited to create a university management system app using Java. I’m looking for guidance on how to approach this project and a roadmap to follow. Here are the key features I have in mind:

App Overview:
The app will cater to three types of users: Admins, Teachers, and Students.

Features:

1. Admin Section:

Ability to add and manage teacher and student profiles.

1. Teacher Section:

• Teacher profiles with assigned classes.
• Attendance page to track student presence.
• Timetable for each teacher.
• Download attendance and student data in Excel format .

1. Student Section:

• Student profiles with personal information.
• Attendance tracking feature.
• Library book issue and return system.
• Fees management page.
• Timetable and assignment tracking.
• Notification system for college updates.

Unique Attendance Feature:

A Tinder-like interface for marking attendance, where teachers can swipe right for present and left for absent. This interactive feature aims to make attendance taking more engaging and efficient.

Questions:

I’m eager to know:

• What steps should I take to get started, and what should I focus on learning first?
• How can I design an engaging UI/UX for the app? Any recommended tools or resources?
• Is it feasible to implement a web version of the app? What technologies should I consider for that?
• Any tips for securely managing user data and implementing the features?

I appreciate any insights or advice you can provide! Thank you in advance for your help!
