The Visualization Core Lab will host an Introduction to SQL for Data Science workshop.
Visualization lab staff will provide an introduction to SQL for data science designed for
learners with little or no previous experience with SQL programming.
Topics covered will include the following.
Sorting and removing duplicates
Calculating new values
Creating and modifying data
Programming with databases-Python
Next steps for more advanced SQL training for data science.
This hands-on lesson is part of the Introduction to Data Science Workshop Series
being offered by KVL as part of our on-going efforts to build
capacity in core data science skills both at KAUST and within the Kingdom of Saudi Arabia (KSA).
The workshop curriculum largely follows the
curriculum developed by
Software Carpentry, a volunteer project dedicated to helping
researchers get their work done in less time and with less pain by teaching them basic research
This is a live-coding based workshop and learners are expected to work along with the instructor using freely
available cloud resources provided by the Binder project.

This will provide you with both Git and Bash in the Git Bash program.
The default shell in all versions of macOS is Bash, so no
need to install anything. You access Bash from the Terminal
See the Git installation video tutorial
for an example on how to open the Terminal.
You may want to keep
Terminal in your dock for this workshop.
The default shell is usually Bash, but if your
machine is set up differently you can run it by opening a
terminal and typing bash. There is no need to
Python is a popular language for research computing, and
great for general-purpose programming as well. While there are many different ways to install
Python, we recommend installing the 64-bit Python 3 version of
We will teach Python using the JupyterLab,
a programming environment that runs in a web browser. For this to work you will need a reasonably
up-to-date browser. The current versions of the Chrome, Safari and
Firefox browsers are all supported.
Download the 64-bit Python 3 installer for Linux. The installation requires using
the shell. If you aren't comfortable doing the installation yourself stop here and
request help at the workshop.

you just downloaded should appear. If it does not, navigate to the folder where you
downloaded the file, for example with:
Then, try again.
Press Return. You will follow the text-only prompts. To move through
the text, press Spacebar. Type yes and press enter to approve
