    When We create an index on the column or columns of a table, Where does this index gets stored in the oracle database & how's it stored ?

    It gets put in a tablespace, like all the other objects in the database. Look up STORAGE parameters too see how and where you can put an index.

    You should place the index in a tablespace different from the tablespace of the table it indexes. Otherwise, all of the I/O is concentrated in one set of files. The performance is better if the I/O is distributed.
