Nowadays the ability of using database is useful not only for programmers. The training PostgreSQL for analysts is recommended for people who are not directly involved in writing the project’s code, but make reports and analyze the data collected by the application.The course leads from the basis of SQL language, through its more sophisticated clauses until specialistic solutions appearing only in PostgreSQL.
After completing the training students will be able to create advanced reports by writing queries directly in SQL language, thus relieving the team of developers. Many statements requiring tedious data export from a database and import to Excel or Access can be quickly and more efficiently generated directly from PostgreSQL.
In the course we take into account the full range of the possibilities offered by PostgreSQL, we discuss the examples of solving the most common reporting problems. The training includes a great amount of exercises.
Our instructors have many years of experience with PostgreSQL, both as administrators and as programmers. One of our trainers is a PostgreSQL contributor and a regular speaker at the world’s largest conference on the topic.

Open training groups are no larger than 8 participants.
Private training can be conducted for groups of any size, according to the Customer's preference. To assure high quality and good learning environment, the group size should not exceed 12.
On-demand training costs and registration
The prices provided in the general tables cover the cost of an open (public) training for one person.
In the case of an on-demand training at the Customer's premises, you are required to provide the necessary facilities (room, computers, projector) and we will send an instructor to run the training. The price for a session is calculated for the whole group.
The cost does not change significantly along with the number of participants. There is no minimum number of participants but we recommend no more than 10-12 people because the training becomes much less effective with a bigger group..
The cost of an on-demand training consists of:
- the base training cost, plus
- travel and accommodation charges for the instructor
The base price of an on-demand training varies, but it is usually around the price of an open training for 3-5 persons (regardless of your group size).
The typical travel and accommodation price for the EU/Schengen zone is under 1250 GBP (1500 EUR) for a 5 day session. We do our best to keep it as low as possible in your location.
The payment can be in GBP or EUR, whichever you prefer. The quotation we will send you with the exact amount in your currency will be valid for 3 months, regardless of any changes in the exchange rate.
For more information, or to register to a group, please contact us at firstname.lastname@example.org and tell us know:
- the course(s) that you are interested in,
- your location,
- your preferred dates,
- the number of people you wish to train,
And any other questions that you may have.
We can also customise the training program of any of our trainings (or create a new one) according to your needs – whether you want to focus on particular solution used in your company, include material concerning a technology we do not usually cover, or create a tailor-made training.
For individual persons for whom all scheduled open training is inconvenient, we offer individual consultation. Virtually all of our training courses are available as such.
During individual consultations, while it can be a direct equivalent of a group training in terms of subject covered, we can also provide more than that – we can solve problems, help choose appropriate solutions and provide advice on the most effective use of chosen tools.
The price includes:
- course materials,
- snacks, coffee, tea and soft drinks,
- course completion certificate,
- one-time consultation with the instructor after course completion.
