What are indexes?

Answer Posted / paramjeet

Indexes are described as a copy of a database table reduced
to specific fields. This data exists in sorted form. This
sorting form ease fast access to the field of the tables. In
order that other fields are also read, a pointer to the
associated record of the actual table are included in the
index. the indexes are activated along with the table and
are created automatically with it in the database.
