Vector Databases Fundamentals to Production [2026 Edition] (Udemy.com)

Amazing job, Paolo, thanks a lot and especially for decision trees, they are priceless and they definitely stand out when I compare your courses to other courses available on Udemy

The instructors explanation is great. His simplification of hard concepts, shows his experience in teaching. I would definitely recommend all his courses, after experiencing 10% of this course, I confidently say that, he is the best at what is he is teaching.

Very good course and clear explanation of the topic of vector databases. It helped me to understand what actually a RAG system is and how to build it.

I recently completed this course, and I must say it was extremely insightful and well‑structured. The content does a great job of covering both the fundamentals and practical aspects of vector databases, making it highly relevant for anyone working with modern AI applications. What I found particularly valuable was the hands‑on approach and the clear explanation of concepts like RAG pipelines, hybrid search, embeddings, and vector indexing, which helped me build a strong conceptual understanding along with practical implementation knowledge. I would highly recommend this course to anyone looking to ease the learning curve in this space. If you’re curious about vector databases or want to develop a solid understanding of how they power modern AI systems, this course is definitely worth exploring.

I can say that the course is good at what it sets out to do, which is to demonstrate the fundamentals of vector databases and tools. I had to learn the concepts in practice, meaning I couldn't finish the course before having to solve a problem, but after dealing with two projects and returning to the course, I can say that it covers the basic concepts that will be used in everyday work.

The instructor is explaining everything clearly and the way this is present is very engaging so far. Looking forward to the rest of the course.

There are no codes provided in python. It’s important for me to get codes in order to follow the lectures and not to waste my time on technical issues. I am very disappointed

I am really enjoying Paulo’s course. His delivery is engaging, and he clearly has a strong understanding of the material. Before this, I took a vector database course from another instructor, but it felt very dry. The content was mostly read directly from slides, which made it hard to stay focused. Paulo’s teaching style is a refreshing change and keeps me genuinely engaged. I am a project manager, so I loved the level of detail he covered in the course. At last, his voice was very soothing, so it was a bonus!

This is the first time I looked at Vector databases and this course gave me lot of confidence that I can use vector database and lang chain very easily. Instructor is excellent in communication and showed everything required to understand vector databases from basics and gave very good overview. I definitely recommend this course to anyone who are new to vector databases , LLM, Langchain.

Python codes shown are working, but after a while different codes are shown compared to earlier. Some challenges on the extensions specially when migrated. After repeated install/uninstall using ChromaDB it worked.
