In the course PostgreSQL Administration participants learn to configure and manage PostgreSQL databases. PostgreSQL is a powerful and robust open source object-relational database system with a good reputation for reliability and performance. The course uses the latest version of the PostgreSQL database and the pgAdmin graphical user interface.
The course PostgreSQL Administration starts with a discussion of the installation options and the tools pgAdmin and psql. Also the main features of PostgreSQL are covered such as table inheritance, sophisticated locking, nested transactions and asynchronous replication.
Subsequently the PostgreSQL Architecture and the processes that play a role in it, such as the Postmaster Daemon Process, Background and Backend Processes and Client Processes, are treated. Tablespaces and vacuum are also covered.
Attention is also paid to the most commonly used server and database objects that PostgreSQL provides. It is important to get to know these objects, such as Server Service and Database Object, in order to be able to use their functionality.
Then it's time for the PostgreSQL backup tools pg_dump and pg_dumpall. Point-in-Time Database Restoration and Setting up WAL archiving are then explained.
The use of indices in PostgreSQL and the differences between the indices B-Tree, Hash, GiSY, GIN and BRIN is also part of the course PostgreSQL Administration.
Securing a PostgreSQL Server is of course of great importance. In that respect access permissions and client authentication control are covered and Data Encryption and the pg_crypto module as well.
Finally attention is paid to High Availability and Load Balancing by placing multiple PostgreSQL servers in a cluster.
The course PostgreSQL Administration is intended for persons who need to administer, monitor and support PostgreSQL databases and servers.
To join the course PostgreSQL Administration knowledge of the SQL query language and databases is needed.
The subject matter is treated on the basis of presentations. Demos are used to clarify the theory and exercises are used to bring the theory into practice. The course times are from 9.30 up and to 16.30.
Participants receive an official certificate PostgreSQL Administration after successful completion of the course.

All our courses are classroom courses in which the students are guided through the material on the basis of an experienced trainer with in-depth material knowledge. Theory is always interspersed with exercises.
We also do custom classes and then adjust the course content to your wishes. On request we will also discuss your practical cases.
The course times are from 9.30 to 16.30. But we are flexible in this. Sometimes people have to bring children to the daycare and other times are more convenient for them. In good consultation we can then agree on different course times.
We take care of the computers on which the course can be held. The software required for the course has already been installed on these computers. You do not have to bring a laptop to participate in the course. If you prefer to work on your own laptop, you can take it with you if you wish. The required software is then installed at the start of the course.
Our courses are generally given with Open Source software such as Eclipse, IntelliJ, Tomcat, Pycharm, Anaconda and Netbeans. You will receive the digital course material to take home after the course.
The course includes lunch that we use in a restaurant within walking distance of the course room.
The courses are planned at various places in the country. A course takes place at a location if at least 3 people register for that location. If there are registrations for different locations, the course will take place at our main location, Houten which is just below Utrecht. A course at our main location also takes place with 2 registrations and regularly with 1 registration. And we also do courses at the customer’s location if they appreciate that.
At the end of each course, participants are requested to evaluate the course in terms of course content, course material, trainer and location. The evaluation form can be found at https://www.klantenvertellen.nl/reviews/1039545/spiraltrain?lang=en. The evaluations of previous participants and previous courses can also be found there.
