What are the differences between internal data and external data?

Ah, internal data and external data are like two different colors on your palette. Internal data is like the colors you mix together yourself, it comes from within your organization. External data, on the other hand, is like the colors you find in nature, it comes from outside sources like market research or public databases. Both types of data are important for creating a beautiful picture of your business, so don't be afraid to blend them together to make something truly special.
