‫Holy moly, that was a lot of information thrown at you.

‫Hopefully you learned something new if you're experienced and hopefully you learned a lot of things

‫if you are just starting out.

‫This is when the course really starts.

‫This is when we start learning some useful skills, ways to use the school to interact with all these

‫databases.

‫So for the rest of the course, as we learn more and more about these, we're going to dive into ask

‫you how it works.

‫And then later on, once we have a good understanding, we're going to revisit this idea of different

‫databases, when to use what how to use something like a key value store like retests, when you should

‫use something like Mongo DB versus PostgreSQL.

‫But the key takeaway is that we first have to ask ourselves, one, do we have useful data?

‫If we do, then we're going to need to ask you all the two is well, in this course, we're going to

‫have to use a database.

‫And for that, you'll see that eventually we're going to show you how to install a database software,

‫a database management system onto your computer so that we can actually store this data.

‫And then finally, we're going to use ask you well, to, first of all, add that data to the database

‫and then use that data to find different interesting things.

‫It's going to be a lot of fun.

‫I hope you're excited.

‫I know I am.

‫Let's dive right in.
