Holds date-specific information about a data entity allowing you to keep track of changes over time.

• A. Master Files
• B. Contacts
• C. Records
• D. Items

Answer: (B)

Tracking changes over time relies on attaching date-specific information to the entity’s record so you can see how details evolve. A contact record is where such history is typically kept—the timestamps for creation, updates, and related changes let you reconstruct past states and understand how the contact’s information has changed. This makes it the best fit for capturing date-specific information tied to that data entity.

Master files are the core reference data and don’t inherently imply historical change tracking for a single entity. Records is a broad term for data rows in general and doesn’t specify built-in history. Items refer to products or objects and likewise focus on current attributes rather than the change history of an entity.
