I Built an AI Data Agent Which Can Query Data and Answer Business Questions. Here’s How.

A step-by-step walkthrough of building a conversational AI data agent using Google Cloud BigQuery's Conversational Analytics API. The demo, called the Avocado Sales Analytics Agent, lets business users ask natural language questions and receive SQL-backed answers without writing any SQL. The guide covers choosing between building from scratch (LangGraph, CrewAI) vs. using managed cloud platforms (Snowflake Cortex, Databricks Genie, Microsoft Fabric), setting up BigQuery with a Kaggle dataset, writing effective agent instructions including metric calculation rules, date handling, and geographic data quality notes, adding verified queries to prevent incorrect aggregations, and wrapping the agent in a lightweight Flask chat app that filters out intermediate reasoning messages from the API response.
