What is the difference between a sedan and a sportsback in Audi cars?

I am looking into buying an Audi car but I am confused about the different types of car models available. Can someone explain to me the difference between a sedan and a sportsback in Audi cars?

A sedan is a traditional four-door car with a separate trunk, while a sportsback has a hatchback-style rear door and a larger cargo area. If you are looking for better storage space, a sportsback would be a better option.
