Dynamic hashing techniques, such as Extendible Hashing and Linear Hashing, allow for efficient file expansion in database management systems (DBMS). Extendible Hashing uses a directory structure that can grow as needed, allowing new buckets to be created without reorganizing existing data. Linear Hashing incrementally splits buckets based on a predetermined growth factor, enabling dynamic adjustment of the hash structure while maintaining efficient access. These techniques help manage variable data sizes and maintain performance as data volume changes.

In dbms what is indexes and hashing techniques?

Indexes in DBMS are data structures used to quickly retrieve data based on specific columns in a table. They allow for faster query processing by reducing the number of records that need to be scanned. Hashing techniques in DBMS involve converting data into a hashed value using a hash function, which is then used to index or organize the data for faster retrieval. Hashing provides quick access to data by generating a unique location for each record based on its hash value.
