1.	Hash structures are not the best choice for which of the following?(a) A search key on which individual point queries are likely(b) A search key which is invalid(c) A search key on which range queries are likely(d) A search key on which multi-level queries are likelyThe question was asked by my college professor while I was bunking the class.Asked question is from Dynamic Hashing topic in portion Indexing and Hashing of RDBMS
Answer» Correct CHOICE is (c) A search KEY on which range queries are likely For explanation I would say: Hash structures are not the best choice for search KEYS on which range queries are likely because the range queries might contain DIFFERENT values of the search keys which might RESULT in improper placement in the hash table.
