Separately, we'd like to track the number of items in stock for each product. To do so we'll have a store and an inventory table. Stores have just an id and a name. Then, our inventory table should combine stores and products, listing how much of each product each store has in stock. a product_id (INTEGER) a store_id (INTEGER) a quantity (INTEGER) in stock Now we can insert some stores, products and inventory into our database. There are 2 stores -- one called NY and one called NJ. There are 2 products we are concerned with. Their names are sneakers, costing $220 (remember this is dollars!) and boots costing $350. Use any description for each that you'd like. NY has 4 sneakers in stock and 3 boots. NJ has 5 sneakers in stock and no boots. Insert the above data into the tables you have created.arrow_forward
