InteLIS Insights

Convert natural‑language questions into SQL for the InteLIS database. Runs a query plan through an LLM, validates the SQL, executes it, and returns results (with privacy rules enforced).

Quick Start

1. Install deps

composer install

1. Export the DB schema (required)

php ./bin/export-schema.php

This generates var/schema.json. Re‑run it whenever the database schema changes.

Use It

• Web UI: open /chat and ask a question.

• API:

  • Ask a question

    POST /ask
    Content-Type: application/json
    {
      "q": "How many VL tests in the last 6 months?",
      "provider": "ollama|openai|anthropic",  
      "model": "optional-model-id"
    }

    Response (minimal shape)

    {
      "sql": "SELECT …",
      "rows": [ { "col": "val" } ],
      "timing": { "provider": "…", "model_used": "…", "total_ms": 0 }
    }

  • Clear conversation context (reset the server-side context window)

    POST /ask
    Content-Type: application/json
    {
      "clear_context": true
    }

    Response

    { "message": "Conversation context cleared", "context_reset": true }

    Note: when clear_context is true, it is handled immediately and any q value (if present) is ignored for that request.

Workflow

High-level flow High-level flow

1. User asks a question (UI /chat or POST /ask).
2. Context is built: user query + conversation history + var/schema.json + business rules + field guide → prompt to the selected LLM.
3. LLM generates SQL (QueryService validates & enforces privacy rules).
4. SQL is executed against MySQL (DatabaseService).
5. Charts are generated based on the query output.
6. Results are returned to the caller (rows, counts, timing, debug info, charts) and conversation context is updated.

Loading

LLM Providers

Works with Ollama, OpenAI, and Anthropic. Pick a provider/model in the /chat settings or send provider/model in the /ask payload.

Notes

• Privacy rules prevent returning disallowed columns.
• If you see “model not found”, use an explicit model id (e.g., for Anthropic use a dated id).
• If SQL generation looks off after schema changes, re‑export the schema (export-schema.php).
