FME's list attributes can be used to let you translate between object-oriented and relational data models.

• A. True
• B. False
• C. Sometimes
• D. Not applicable.

Answer: (A)

List attributes in FME store multiple values under one attribute on a single feature, representing a collection. This matches object-oriented thinking, where an object can have a property that is a list of items, and it also maps to relational thinking, where a one-to-many relationship is represented by multiple related rows. By collecting related items into a list attribute, you can represent the object-side structure, and by expanding that list into separate records, you can recreate the relational side. So, using list attributes enables translating between object-oriented and relational data models, making this statement true. For example, a single feature with a list of phone numbers can be mapped to separate phone number rows in a related table.
