How k-kabeesan/labbooker works

LabBooker is a Qt desktop system for laboratory reservations and administration. Users sign in, check availability, request or manage bookings, and track decisions; administrators also manage accounts and resources, configure schedules, and produce reports. The graph separates UI, domain services, and SQLite persistence. Some page-to-service wiring is not shown in the excerpts, so those links are dashed and unverified rather than asserted as calls.
