Oracle Managing Indexes
As defined by oracle we have following indexes.
1) B-Tree Index : By far the most common one.
2) B-Tree Cluster : Index defined for cluster.
3) Hash Cluster : Index defined for Hash Cluster.
4) Global and Local Indexes : Relate to partitioned table and indexes.
5) Reverse key Indexes : most usefulll for RAC
6) Function-Based
7) Domain indexes.
We will mostly deal with B-Tree Index
