Explain extnsively how each of the 8 cost estimation techniques: (1) Linear search on a heap file that has no index (2) Binary search on a sorted file that has no index (3) Equality search on an attribute that has a hash index (4) Equality search on an indexed primary key (5) Inequality search on an indexed primary key (6) Equality search on an indexed (clustered) non-primary key (7) Equality search on an indexed (non-clustered) non-primarykey (8) Inequality search on an indexed (B+Tree) non-primary key can be combined with various heuristic rules during query optimization by the DBMS and the effect this has on reducing the workload of a DBA
