The 4 best PostgreSQL courses in 2026

Stop stitching three databases together. HelixDB is a Rust-native graph plus vector engine that holds your nodes, your embeddings, your typed edges, and your key-value documents in one process — no separate Postgres, no separate Qdrant, no separate Neo4j. This course walks a Rust-fluent engineer from helix init through a typed HelixQL schema, the helix check and helix compile pre-deploy gates, side-by-side graph traversal and vector search in the same query language, and a typed Rust client that calls a live HelixDB instance with four runtime contracts. Every primitive you meet is wired into a

By the end of this course, learners will be able to explain PostgreSQL fundamentals, apply SQL commands to manage databases and tables, design relational structures using constraints and keys, and modify existing tables safely in real-world environments. This course provides a structured, hands-on introduction to PostgreSQL, one of the world’s most powerful open-source relational database systems. Learners progress from understanding PostgreSQL architecture and database management basics to inserting data, applying constraints, using SQL operators, and designing well-structured tables. Advanc

Learners will apply SQL concepts, analyze real-world e-commerce datasets, and produce business-ready reports using PostgreSQL. By the end of this course, learners will be able to design relational database structures, write optimized SQL queries, perform advanced aggregations, and generate actionable insights from transactional data. This course provides a hands-on, project-driven approach to mastering PostgreSQL for data analysis. Learners begin by setting up the PostgreSQL environment and building a strong foundation in database management, table design, data types, and constraints. They th

This is a self-paced lab that takes place in the Google Cloud console. In this lab, you migrate a stand-alone PostgreSQL database (running on a virtual machine) to AlloyDB for PostgreSQL using a continuous Database Migration Service job with VPC peering for connectivity.
