#75: The "Key" To Building A Reliable Data Model

There are a lot of things to consider as you're building a data model.

Performance, naming, scheduling, etc.

But one thing you cannot overlook is establishing relationships between your tables.

Otherwise, you don't really have a model - you just have a bunch of disconnected data points.

And a major part in this process is determining the unique identifier in each of your warehouse tables.

It can determine how useful your model becomes and how well it can scale.

So in this video, we're going to talk about a "key" topic known as the Surrogate Key.

We'll talk about:
- What they are
- Why they're important
- And why you might want to consider using them for your own modeling, if you haven't already

Enjoy.
