I have participated in the development of the self-briefing system to support operational units such as ATCs (Air Traffic Controllers). This enables ATCs to prepare before starting their shift by accessing relevant information such as NOTAMs, SNOWTAMs, VIPs, mandatory documents, or various announcements that they need to be aware of. It also allows tracking of user license information, including the status of the license and when it needs to be renewed. The system efficiently manages user data, with various levels for dividing work responsibilities and access rights to data or different pages. Furthermore, it keeps logs of various user activities for future reference.
