What is hash file organization? What are the causes of bucket overflow within a hash file organization? What can be completed to decrease the occurrence of bucket overflow?
Hashing includes computing the address of a data item through computing a function on the search key value. A hash function h is a function from the set of all find out key values K to the set of all bucket addresses B.
We choose a number of buckets to correspond to the number of search key values we will have stored within the database. To perform a lookup on a search key value K, we compute h(Ki i), and search the bucket along with that particular address.
If two search keys i and j map to the similar address, because, h(K)=h(K) then the i j bucket at the address acquired will contain records along with both search key values.
The hash functions selected should be such in which it should result in uniform distribution of search keys.
