Postgresql Training

Postgresql Admin & Developer Training 

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

Postgresql Database Administration

To effectively leverage Postgresql you need to know

  • how to monitor and maintain a healthy cluster,
  • how to set up replication and backups.
  • how to perform backups and point-in-time restores,
  • understand popular extensions and their usage,
  • and more.

See our Postgresql  Database Administration training course for more details.

Postgresql Developer Training

To get the most out of the rich Postgresql API, features, and extensions developers need to know how to:

  • write optimised psql procedures,
  • install, use and create extensions,
  • write procedures in your preferred language,
  • define new data types,
  • define new functions,
  • leverage unique data types such as json, xml and hstore

See our Postgresql Developer training course outline for more details.

Postgresql Developer Training

Postgresql Developer Training

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.
