Direct file organization

Direct file organization— organization of files based on a unique for each file, which is accessed directly through the memory address of the key. Direct file organization allows data to be retrieved quickly in a random manner, regardless of the way in which the data was originally stored. In this method, the unique key that is used to organize files (such as social security number) is converted directly to a memory address, using a mathematical formula called a hashing algorithm.
