Description
Unlock the power of AI + Databases with this hands-on course on LangChain, PostgreSQL, and Conversational AI.In today’s world, AI is not just about generating text — it’s about connecting intelligent language models with real-world data. This course is designed to take you step by step from the fundamentals of AI to building production-ready AI agents that can query databases, understand natural language, and return user-friendly results.You’ll start by setting up your Python environment and learning the essential AI libraries. Then, you’ll connect to PostgreSQL, run test queries, and integrate your database with LangChain, the powerful framework for LLM applications.Through practical examples and real code, you’ll discover how to:Wrap PostgreSQL with LangChain’s SQLDatabaseChain.Convert natural language questions into SQL queries automatically.Build safer querying pipelines with predefined queries and intent classification.Add memory so your AI can hold conversations with context.Use agents and LangGraph for advanced, multi-step reasoning.Engineer prompts for schema-aware SQL generation and debug queries effectively.Deploy your chatbot with Streamlit and FastAPI for interactive apps and APIs.By the end of this course, you’ll have the skills to design and deploy your own AI-powered database assistant — from a simple chatbot to an advanced agent that reasons about data safely and efficiently
