Data Science Jupyter Notebooks

Discussion and Potential Improvements:
Real Barcode Scanner: This application works directly with a USB barcode scanner. A scanner acts as a keyboard, so when it scans a code, it types the numbers and sends an "Enter" keystroke, which perfectly triggers our returnPressed signal.
Data Integrity: We added a basic check for stock (quantity > 0). A more robust system would check if the quantity in the cart exceeds the quantity in stock before allowing the sale to complete.
Features for a Real Pharmacy: A production-level system would need many more features: prescription management, patient records, batch tracking for recalls, advanced reporting (e.g., top-selling drugs, low-stock alerts), user accounts with different permission levels, and receipt printing.
Database: SQLite is perfect for a single-user, standalone application. For a pharmacy with multiple terminals, a client-server database like PostgreSQL or MySQL would be necessary.

This project provides a solid foundation, demonstrating how to integrate hardware (like a barcode scanner) with a database-backed desktop application to solve a real-world business problem.
