2. Backend: FastAPI server handling API requests, database queries, and PDF processing
3. Database: SQLite for storing survey data
4. PDF Storage: Local server directory or cloud storage (e.g., AWS S3)
5. NLP Model: OpenAI API or open-source alternative for natural language processing

Key components:
