AI Analytics Engine with Spring AI: Questions to Charts

Modern applications are no longer limited to dashboards built manually by developers. Today, users expect to ask questions in plain language and instantly receive meaningful insights, summaries, and visualizations.In this course, you will build a complete AI-powered analytics engine using Spring Boot and Spring AI that converts business questions into SQL queries, structured insights, and charts automatically.This is not a chatbot tutorial. This is a real backend system designed using production-grade architecture, reliability principles, and proven engineering practices.By the end of this course, you will have built a system that accepts natural language questions, generates safe and validated SQL using LLMs, interprets database results into meaningful insights, and renders charts automatically in a web interface.Everything is built step-by-step using Java, Spring Boot, PostgreSQL, and Spring AI.Includes free 90-day access to IntelliJ IDEA Ultimate for a professional development experience.Includes professionally prepared subtitles in Spanish, Portuguese (Brazil), Japanese, and Chinese.What You Will BuildYou will build a complete AI analytics pipeline with the following flow:Question → AI generates SQL → SQL validation → Database execution → AI interprets results → Insight JSON → Charts rendered automaticallyThe system will include:• Natural language question input• Automatic SQL generation using Spring AI• SQL validation using a parser to ensure safety• Dynamic schema reading from the live database• AI-generated summaries, findings, and recommendations• Automatic chart generation based on analysis patterns• Simple web interface that renders insights and charts• Deterministic configuration for consistent and reliable output• Protection against vague or unsafe questionsThis mirrors how real AI analytics systems are built in production.Why This Course Is DifferentMost AI courses focus on basic prompt examples or simple chatbots.This course teaches how to design and build a complete AI analytics backend using proper architecture and engineering discipline.You will learn critical engineering principles such as:• Generating SQL safely using LLMs• Validating LLM output before execution• Reading database schema dynamically at runtime• Converting raw database rows into structured business insights• Generating chart-ready data automatically• Making AI systems reliable and deterministic• Evolving intelligence using prompts without changing infrastructureThese are essential skills for building real AI systems.End ResultBy the end of this course, you will have built a complete AI analytics engine that:• Accepts business questions• Generates and validates SQL safely• Produces meaningful insights automatically• Generates charts automatically• Adapts dynamically to database schema changes• Ensures reliable and deterministic behaviorThis project can serve as a foundation for real analytics products, internal tools, or enterprise AI systems.
