Explain the Dynamic Hashing Techniques

There are two methods in it: extendible hashing - stores an access structure in addition to the file, and therefore is somewhat identical to indexing. The major difference is that the access structure is based upon the values that the result after application of the hash functions to the search field. The second one is, linear hashing - does not need additional access structures.
