All right, so database models, this is something we've seen come back again and again.
And in essence, a data base model is nothing more than a way to organize and store your data, but
it also does so much more than that.
That core definition explains only a portion of what's going on here.
And there are many, many database models out there.
To list some here, you have hierarchical networking entity, relationship, relational, object oriented,
flat, semi structured, et cetera, et cetera.
There are many, many models out there that you can use.
And a lot of these models are designed with rules and concepts in place that allow you to create a view
of the data that you're going to store.
Now, the one that we will be looking most at throughout the course is relational because it is still
to this day one of the most popular and widely used models out there.
But I selected two other models that I thought were very important to look at their slightly outdated
and they were popular way back in the 70s and 80s.
But they hold a core foundation of where we started to where we are now.
So we'll be taking a closer look at hierarchical and networking.
Let's get into it.
