Hashed files _____.
A) are stored in physical sequence based on the hashed field values

C) never need to be reorganized
D) can also have indexes built over them
E) cannot also have indexes built over them

Question

Quizplus · Accepted Answer

Hashed files can have indexes built over them, allowing for quick access to data based on specific field values. Option A is incorrect because hashed files are not necessarily physically stored in sequence based on the hashed field values. Option B is incorrect because hashed files can only have one hash function applied to them, whereas indexed files can have multiple indexes built on different fields. Option C is incorrect because hashed files may still need to be reorganized in certain circumstances. Option E is incorrect because, as previously stated, hashed files can have indexes built over them.
