The physical location of a record is determined by a mathematical formula, which transforms a file key into a record location in ____________.
The physical location of a record is determined by a mathematical formula, which transforms a file key into a record location in ____________.
The correct option is C Hashed file
The physical location of a record is
determined by a mathematical formula, which transforms a file key into a record
location in hashed file.
Hashing is the
transformation of a string of characters into a usually shorter fixed-length
value or key that represents the original string. Hashing is used to index and retrieve items in a database because it is faster to find the item using the shorter
hashed key than to find it using the original value.
Hashing technique comes into picture. Hashing is an efficient technique to directly search the
location of desired data on the disk without using index structure. Data is
stored at the data blocks whose address is generated by using hash function.
