Technical Requirements

This section outlines the technical infrastructure, hardware, software, and development tools required to support the DriverPass system. These technical specifications outline requirements to keep the application secure, scalable, and responsive across all user roles. By defining these requirements upfront, development teams have the blueprints to build a system that meets that meets the needs of DriverPass.

Technical Requirements for DriverPass System

1. Hardware Requirements

Cloud-hosted virtual servers

Containing scalable CPU and RAM to support multi-user load.

Client Devices:

Mobile devices (smartphones/tablets with cellular or Wi-Fi connectivity)

Drivers: used to log post-lesson notes on-the-go, communicate with students and route to pickup locations.

Desktop or laptop computers

Secretaries and IT Admins: used to manage schedules, user accounts, and security audits.

Web-enabled devices (desktops, laptops, smartphones)

Students: used to view dashboards and training materials.

2. Software Requirements

Operating System:

Server

Linux for robust security, stability, and scalability.

Client

Cross-platform web browser support (Chrome, Safari, Edge, Firefox) across iOS, Android, Windows, and macOS.

Database Management System:

Relational Database System to manage structured entities like User, Student, Driver, DrivingLesson, TrainingPackage, and Vehicle.

Application Framework:

Enterprise web framework to implement core controllers and RESTful APIs connecting the user interfaces with the database.

3. Tools and Third-Party Services

Design & CASE Tools:

Lucidchart (used for system modeling and UML diagram creation).

Notification API:

Integration with automated SMS/Email gateways to send lesson booking confirmations and schedule updates to students and instructors.

Reporting Tools:

Spreadsheet export library enabling business owners to export logs and reports to Microsoft Excel.

4. Infrastructure & Security

Security & Authentication:

HTTPS/TLS encryption for all data in transit.
Encryption at rest for database records containing sensitive customer and permit data.
Role-Based Access Control (RBAC) to enforce security boundaries between roles

Backup & Monitoring:

Automated daily database backups with point-in-time recovery and security monitoring tools for IT audit logging.
