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.
Link list representation of a circular queue is more efficient as it employs space more competently, of course with the added cost of storing the pointers. Program 7 gives the link
How to create multiple queue on single array?
Step 1: Declare array 'k' of size 'n' i.e. k(n) is an array which stores all the keys of a file containing 'n' records Step 2: i←0 Step 3: low←0, high←n-1 Step 4: while (l
B i n a ry Search Algorithm is given as follows 1. if (low > high) 2. return (-1) 3. mid = (low +high)/2; 4. if ( X = = a [mid]) 5. return (mid); 6.
An interesting application or implementation of trees is the playing of games such as tie-tac-toe, chess, nim, kalam, chess, go etc. We can depict the sequence of possible moves

Define data model? A data model is a collection of conceptual tools for explaning data, data relationships, data semantics and consistency constraints.
Since memory is becoming more & cheaper, the prominence of runtime complexity is enhancing. However, it is very much significant to analyses the amount of memory utilized by a prog
The process of accessing data stored in a serial access memory is same to manipulating data on a By using stack method.
Limitation of Binary Search: - (i) The complexity of Binary search is O (log2 n). The complexity is similar irrespective of the position of the element, even if it is not pres
