About Course

Let me take you back to 2009:

Back then, I thought I had it all figured out. I had just finished my master’s degree and thought, “Now I’m ready to work on any data project and be the best.

But then I joined my first project and walked into a meeting where I heard so many words that I had no idea what they meant. I began to feel insecure.

The month didn’t get better. In fact, it got worse. By the time the on-boarding was over, I was sitting there with all these tools, terms, tasks, and I was really frustrated.

Fortunately, I met some great people along the way who had the willingness and talent to share their knowledge about things that just seemed weird to me. So I found help in simple words and precise examples. Finally, I began to understand.

Can you relate to my story? Maybe you are at this point now. Then I want this for you.

I would love to be one of those coaches on your journey to mastering data, SQL, and databases.

What can you expect to learn in this course?

  • We will start at zero, 0, null. Promised!
  • Use lots of examples and small steps to build your skills.
  • Sprinkle in a lot of exercises and repetition.

If you ever get stuck, don’t hesitate to send me a message.

We can walk this path together.

I really look forward to seeing you in this course!

  1. Separate Table: Create a table for tags (name, object_id) to link tags to objects.,
  2. Array: Store tags as a text array in your main table’s dedicated column.,
  3. hstore (extension): Use key-value pairs (tag name as key, details as value).,

Choose based on:,

  • Tag complexity: Need extra data with tags? (hstore),
  • Number of tags: Expect many tags per object? (Array might be efficient),
  • Querying tags: Frequent searches based on tags? (Array with GIN index),
