Right Answer:
A lookup file is a static reference file used to retrieve additional information based on a key value during data processing. It is typically smaller and used for quick lookups. A join, on the other hand, combines two or more datasets based on a common key, merging their records into a single output. The key difference is that a lookup file is used for referencing data, while a join is used for combining datasets.
