PostgreSQL Tutorial Full Course 2022

I provide here in this PostgreSQL tutorial a full course you can use to master PostgreSQL. Postgres is an object relational database that is just as fast as MySQL that adheres more closely to SQL standards and excels at concurrency. Postgres is also superior at avoiding data corruption.

Today we announced the general availability of SQL Server 2016, the world’s fastest and most price-performant database for HTAP (Hybrid Transactional and Analytical Processing) with updateable, in-memory columnstores and advanced analytics through deep integration with R Services. Software applications can now deploy sophisticated analytics and machine learning models in the database resulting in 100x or more speedup in time to insight, compared to deployments of such models outside of the database.
