e-TRB functions as an Electronic Record Book designed for educational institutions to oversee students participating in onboard training. The system comprises two applications: a mobile app and a web app. The mobile app caters to cadets and officers, offering the flexibility to function offline or online.

Regarding the process of updating daily records, both applications operate harmoniously. They can function independently or complement each other seamlessly. The sole prerequisite for synchronization is establishing an internet connection for the mobile app.
