Which database technique sets up references on certain columns so repeated queries run faster?
Applying hashes to the columns
Creating an index on columns used often in queries
Removing repeated data from the design
Splitting large tables into multiple sections for faster reads
The specialized structure needed here is known as an index. By creating a direct reference path, queries locate matching rows faster. Splitting large tables into sections helps manage data quantity but does not build a direct lookup path for repeated column queries. Removing repeated data from the design (normalizing) prevents redundancy yet does not specifically accelerate searches. Applying hashes to columns transforms values but does not map entries to rows for quicker retrieval.
