Relational Model – Simulation (Teradata context)

A local educational application (Python + pandas + Streamlit) demonstrating:

- Relational algebra: σ, π, ⋈, δ, ×, ∪, ∩, −, ÷, AC

- Dependencies: functional (FD) and inclusion (IND/foreign key), candidate keys

- Normalization: denormalization → decomposition (3NF/BCNF) → lossless join check

Run locally:

pip install -r requirements.txt streamlit run app_final.py

The application runs fully locally with no deploy/cloud connection.

The UI has been cleaned of the original Streamlit menus and footer.
