## Instruction

Hello and welcome! Today, we're finally going to define the windows of window functions in detail.

Let's start by introducing today's tables. We're going to work for a company called ColdLikeHell which deals with... well, everything that is somehow connected to ice. Let's check the products.

## Exercise

Select all the information from the product table.

Just take a look at all those wonderful products! Each of them has an id, a name, and a third column which informs when it was introduced to the market.
