This course takes 3 days with 8 hours each (on site) or 4 hours each (online).
The only difference is that there will be less practical exercises in an online course. However, we will hand them over to you and you can still do them on your own and ask our consultants for feedback or help if needed.

During this course you will learn how to use PostgreSQL for business intelligence related tasks. In this workshop you will learn to import, process and effectively analyze large amounts of data. You will learn the basic SQL techniques and how to efficiently model mass data. Additionally, you will learn how to integrate external business logic directly into PostgreSQL.

This course is aimed at data analysts and developers who already know the basics of SQL and who face the challenge of having to deal with complex problems or large amounts of data efficiently.

This course can be held in English and German.
