Databases and SQL for Data Science
|Hybrid (In-Person & Live Webinars)||11, 13, 15, 18, 20, 22 July 2021||07:00 PM - 08:30 PM||Dubai Knowledge Park||3,500 AED|
Much of the world’s data resides in databases. SQL (or Structured Query Language) is a powerful language used for communicating with and extracting data from databases. Working knowledge of databases and SQL is a must if you want to become a data scientist.
The purpose of this course is to introduce relational database concepts and help you learn and apply foundational knowledge of the SQL language. It is also intended to get you started with performing SQL access in a data science environment.
The emphasis in this course is on hands-on and practical learning. Indeed, you will work with real databases, real data science tools, and real-world datasets. Moreover, you will learn how to create your own database instance in the cloud. Through a series of hands-on labs, you will practice building and running SQL queries. You will also learn how to access databases from Jupyter notebooks using SQL and Python.

I've attempted to learn similar skills in my own time in the past, and have always found it difficult to persist beyond the beginner level. The course at Innosoft is intensive - 3 hours a day, over 10 days. This immersive approach, in my view, is the absolute best way to learn these difficult skills. The instructor took me from an absolute beginner to being able to fully engage with the Data Science literature available now, both from a theoretical and a coding point of view.
