# DataBot – ERP Database Assistant

DataBot lets you ask **natural-language questions** about your ERP database.
It uses GPT-4o to translate your question into SQL, executes it safely on your
MySQL database, and returns a plain-English summary.

## Features

- Natural-language → SQL → plain-English answers  
- Whitelist-based table access control (`data_access_config.json`)  
- Blocks all write operations (INSERT / UPDATE / DELETE / DROP …)  
- Masks sensitive columns (passwords, IBAN, salary, PII)  
- Schema cached at startup for fast responses  

## Setup (Hugging Face Spaces)

Set the following **Secrets** in your Space settings
(*Settings → Variables and secrets → New secret*):

| Secret name    | Description                           |
|----------------|---------------------------------------|
| `DB_USER`      | MySQL username                        |
| `DB_PASSWORD`  | MySQL password                        |
| `DB_HOST`      | MySQL host IP / domain                |
| `DB_NAME`      | Database name (default: `dev_poly`)   |
| `OPENAI_API_KEY` | Your OpenAI API key                 |
| `LLM_MODEL`    | Model to use (default: `gpt-4o`)      |
