Question: I have studied hashing in DBMS (extensible, linear) and about Indexing in DBMS (sparse, dense, indexes based on secondary key, etc.), but I am unable to understand what the difference is between Hashing and Indexing. Are these two techniques used together ... seem to be to enable us to retrieve the data quickly, so I think either should be sufficient. Can anyone clarify the difference?
