Indexes in Oracle are:
(create <type of index> index <indexname> on <tablename>
(<colname>)
1. B-Tree (regular indexing algorithm )
2. Bitmap (for low cardinality fields.
By default oracle creates bitmap Index)
3. Partitioned indexes (for manageability
and to distribute I/O evenly)
4. Function based indexes (when you want
to index a function based calculation itself)
5. IOTs (Index organised tables - Table and
Index combined into one)
6. Domain Indexes (using user defined index types)
