An Introduction to SQL (with R)

Course Level: Intermediate

Using databases is a fundamental part of a data scientists role. The main focus of this training course is to introduce SQL databases and how R can be used to retrieve and manipulate data stored in a relational database.

We use the PostgresSQL database as an example for public courses. For in-house training, we are happy to adapt the course to match your database requirements.
