Do You Need a Date Dimension?

In the world of data modeling, date and time are incredibly important concepts.

They play a role in pretty much everything we're trying to analyze.

For example:

• When certain transactions or events happened
• Financial trends over time
• Comparing volume totals over different periods
• etc.

But when it comes to actually handling this in a data model, it can get a bit tricky.

This is where the idea of a "Date Dimension" comes into play.

So in this video we're going to talk about why this specific Dimension table is something you may want to consider.

And talk through examples of common data points to include.

Enjoy!
