Joining parts and inventories

The LEGO data has many tables that can be joined together. Often times, some of the things you care about may be a few tables away (we'll get to that later in the course). For now, we know that parts is a list of all LEGO parts, and a new table, inventory_parts, has some additional information about those parts, such as the color_id of each part you would find in a specific LEGO kit.

Let's join these two tables together to observe how joining parts with inventory_parts increases the size of your table because of the one-to-many relationship that exists between these two tables.
