Hello! I’m happy to meet you.

Thanks for dropping by!

My name is Donabel, but I usually go by sqlbelle in social media.

I am a data geek. I work with data, and I teach data, and I am here to share practical tips, lessons that can help you elevate your data skills.

While it was an unexpected journey that led me to working in the data field , it was one of the best detours.

I teach Tableau and SQL

Want to get better working with data using Tableau and SQL? I can help you.
Here are some comments people have left for my YouTube video tutorials on Tableau and SQL

Your videos contributed so much to me getting a new JOB as a DATA VISUALIZATION ANALYST in the midwest region in US

Yet another wonderful explanation on a subject. You are quickly becoming my favorite Tableau teacher. Please keep it coming!

Very good explanation. Very "granular" !!!!! You're a good teacher, very clear and thorough, and "easy to digest". Best explanation I've run across on the web. This is the LOD video I'll share with others. Thanks!!!!

Countless others have commented on how phenomenal your videos are, and I couldn't agree more. Your explanation skills are absolutely sublime; your structuring of videos are par none.

I have more than six years of experience with tableau, I was thinking of making some videos for my students, but as far as I found your videos, I thought that is not necessary anymore. Your videos are incredibly helpful

Really like your Tableau training videos. They are systematic, well structured, and the key points are highlighted. For me they are the most efficient way to learn Tableau

I wanted to know a bit about how to use parameters but I got a whole lot more!! It's jam packed with so much information, extremely practical and very easy to follow along. Thank you very much!

You are one of the best teachers.. Your way of teaching is awesome.. I have seen these concepts and similar examples by others but did not understood the concept.. Now It is clear for me..
DB

As always, something for everyone here. Just when I thought I knew this cold, you show me something new. Thanks and I am looking forward to your next tutorial.

I took a whole Tableau course on UDemy, yet I still come here to clear up difficult concepts and the nitty gritty topics that the other instructor just breezed by.
FA

Absolutely amazing Donabel! Thank you for sharing. You're 10X better at explaining than most paid video courses on LOD's.

Best part your teaching is how to relate the business use cases to the technical functionality. Just amazing!

I started with SQL …

I started my career as a SQL developer, and was very active in the SQL community in the past.

SQL belle aka sqlbelle

I love working with SQL Server. It’s my first “tech” love. Once I started working with data, it’s ins and outs, I was hooked.

I used to be quite active in the SQL Server space. In the early days of twitter, when I used to tweet about SQL Server, I put SQL and my nickname “belle” together, hence the name sqlbelle.

… and stumbled upon Tableau

Lately I am more active and visible in the Tableau #datafam community.

My first encounter with Tableau was when I had to take a Tableau course with Dan Murray from Interworks - check out my first awesome Tableau dashboard.

For me it was just another tech class I had to take. But Dan was so passionate about Tableau, and he convinced me to go to the Tableau conference that year. He said he knows it will change my life. And it did.

Currently, I still use Tableau at work. I’ve also taught it at the British Columbia Institute of Technology (BCIT), at the University of British Columbia (UBC), and online through my YouTube channel.
