It offers an effective way to organize data while there is a requirement to access individual records directly.
To access a record directly (or random access) a relationship is utilized to translate the key value in a physical address. It is called the mapping function R.
R(key value) = Address
Direct files are stored onto DASD (Direct Access Storage Device).
A calculation is carrying out on the key value to get an address. This address calculation technique is frequently termed as hashing. The calculation applied is called hash function.

It does not have any cycles (circuits, or closed paths), which would imply the existence of more than one path among two nodes. It is the most general kind of tree, and might be co
We might sometimes seek a tradeoff among space & time complexity. For instance, we may have to select a data structure which requires a lot of storage to reduce the computation tim
