External data is data that is collected from outside of an organization. It can be collected from a variety of sources, such as government agencies, industry associations, and trade publications. External data can be used to track trends, identify new opportunities, and make informed decisions about business strategy.

The market forecast file contains data on future sales and revenue. The forecast allocation file contains data on how sales and revenue are allocated to different products and services. The customer file contains data on customers, such as their contact information, purchase history, and preferences.

None of these files contain external data.
