Postgresql is rapidly replacing the traditional go-to databases in the enterprise space for workloads from the traditional back-end store for enterprise applications to  big data workloads for machine learning and AI.

Postgresql implements and extends the SQL standard and has become a data platform with a rich feature set that allows developers and engineers to create solutions that simply are not possible on the traditional databases.

Replacing existing databases or using Postgresql as a foundation for your application requires resources with skills in

• Postgresql database administration (dba) and,
• Postgresql development with knowledge of APIs, unique data types and extensions

Essential skills for a Postgresql administrator include the ability to optimise data storage, locations, improve query performance via index management and query plan analysis as well as setting up a robust backup policy and implementing replication. All of these skills are covered in our Postgresql database administrator course.

Whether you have database admin experience in another database or new to database administration this course will provide you with the skills you need to successfully manage your Postgresql cluster.

Postgresql can best be described as a database platform rather than a database server. For decades developers have been taught to create database-independent applications, programming to the most widley implemented SQL standard. With a commercial database this was a sound approach to avoid vendor lock-in event though many of the benefits of database-specific functionality were given up.

With Postgresql this is now no longer a constraint. Postgresql is feature-rich, offering many extension and integration points that afford developers the opportunity to create truly unique applications and solutions.
