How sahilkavathekar7070-cyber/streamlit_demo works
This is a Streamlit railway-reservation application with booking, PNR search, cancellation, and administrative records as its main user workflows. The README describes fare calculation, validation, seat allocation, and CSV export; sampled code confirms the single-file application, SQLite connection and booking tables, seat-availability queries, booking persistence, and PNR lookup. The source excerpt is incomplete, so edges for unsampled workflow details rely on the README’s explicit architecture and capability descriptions; implementation details beyond that are not inferred.
