How it works
DP-3021 is a practical Microsoft Applied Skills course for professionals who need to operate PostgreSQL on Azure. In one instructor-led day, you will examine how PostgreSQL works, configure security and server settings, diagnose query performance, manage concurrency, and plan an offline migration to Azure Database for PostgreSQL.
PostgreSQL combines a mature relational database with an open extension ecosystem, making it relevant to both established production systems and new AI applications.
Databricks announced its approximately $1 billion acquisition of serverless Postgres company Neon in May 2025. Snowflake also announced its acquisition of PostgreSQL specialist Crunchy Data in June 2025; that deal's value was not publicly disclosed.

PostgreSQL was the most-used database among professional developers in Stack Overflow's 2024 Developer Survey, continuing its lead for a second year.

PostgreSQL and Databricks skills increasingly overlap. Lakebase is Postgres-based and powered by Neon technology, so teams building operational AI applications can benefit from understanding both ecosystems. Explore our Databricks training and consulting options.
Explore Databricks trainingPostgreSQL can store application data and, with pgvector, vector embeddings used for semantic search and retrieval-augmented generation. This lets many teams support relational and AI search workloads in one familiar database platform.
pgvector is an open-source PostgreSQL extension for storing embeddings and running vector similarity searches. Azure Database for PostgreSQL supports the extension for AI search and RAG scenarios.
Lakebase is Databricks' managed, Postgres-based operational database, built on technology from Neon. It connects PostgreSQL application workloads with the broader Databricks data and AI platform.
No advanced PostgreSQL experience is required. You should understand relational database concepts and basic SQL before attending.
DP-3021 is Microsoft Official Course content aligned to the Microsoft Applied Skills credential, Configure and migrate to Azure Database for PostgreSQL. The credential uses an interactive lab assessment rather than a traditional certification exam.
You will learn PostgreSQL architecture, client-server communication, query plans, security, procedures and functions, write-ahead logging, configuration, concurrency, Query Store performance tuning, and offline migration to Azure Database for PostgreSQL.
