What algorithm can't be reversed?
Hashing can't be reversed.
What is Hash file organization in DBMS?
Hashing is the most common form of purely random access to a file or database. It is also used to access columns that do not have an index as an optimisation technique. Hash functions calculate the address of the page in which the record is to be stored based on one or more fields in the record. The records in a hash file appear randomly distributed across the available space. It requires some hashing algorithm and the technique. Hashing Algorithm converts a primary key value into a record address. The most popular form of hashing is division hashing with chained overflow.
Which hashing function uses 160-bit digest?
SHA-1 is a function that uses 160-bit digest.
What are the difference between static and dynamic hashing in DBMS?
Search operation in static hashing is time consuming, but in dynamic hashing it is not.
What are the two names of the most popular hashing algorithms?
Both SHA-1 and MD5 are good hashing algorithms. The primary difference between the two is speed; MD5 is faster to process than SHA.
What are different types of hashing techniques are there in DBMS?
there are 2 types of hashing techniques 1- Static hashing 2-Dynamic hashing
What is Homomorphic Hashing?
Homomorphic Hashing is a algorithm technique used for verifying data.

Explain the distinction between closed an open hashing discus the relative merits of each technique in database application?
Closed hashing involves storing all key-value pairs directly in the hash table, while open hashing involves using separate data structures (such as linked lists) to handle collisions. Closed hashing typically has better memory management and faster access times for non-colliding keys, while open hashing can handle a larger number of collisions without needing to resize the hash table. In database applications, closed hashing may be preferred for smaller datasets with minimal collisions, while open hashing may be more suitable for handling large volumes of data with frequent collisions.
Explain the distinction between closed an open hashing Discuss the relative merits of each technique in database application?
A hash table is where data storage for a key-value pair is done by generating an index using a hash function. Open Hashing (aka Separate chaining) is simpler to implement, and more efficient for large records or sparse tables. Closed Hashing (aka Open Addressing) is more complex but can be more efficient, especially for small data records.
What is hashing in Java?
Creating a Integer out of an object is called hashing. Hashing is commonly used in HashTable, HashMaps and HashSet. For instance you have Alex John Peter Hashing on each value would generate something like 123455 Alex 123344 John 123987 Peter when put in hashtable or hashset would be quicker to find each piece of information. There are many algorithms available with java to get the hash of an object.
