Which data type is commonly used to represent a globally unique identifier in Clarity?

• A. Boolean
• B. Date
• C. Integer
• D. GUID represented as uniqueidentifier

Answer: (D)

A globally unique identifier is stored as a uniqueidentifier (GUID) in Clarity. GUIDs are 128-bit values designed to be globally unique across systems and time, which makes them ideal for keys in distributed environments. The uniqueidentifier type is built to hold this kind of value and is treated as a single identifier, not as a boolean, date, or integer. Boolean stores true/false, Date stores calendar timestamps, and Integer stores whole numbers. None of these provide the 128-bit structure and global uniqueness guarantees of a GUID, so the data type that specifically represents a GUID is the appropriate choice.
