Question:
What is the main use of hashing in databases?
A
For indexing and retrieval.
explanation
Hashing is commonly used in databases to increase the speed of indexing and retrieval since it is typically faster to search for a hashed key rather than the original value stored in a database. Hashing is not a form of encryption, meaning that it is not used to encrypt stored data. Hashing is not used to obfuscate data or to substitute for sensitive data.
