In general the same index theory applies to DW as it is for
any RDBMS. So we can have one clustered index and several
non-clustered indexes on a table. defininng the index
depends on the need for the particular SQL. We usually
define them on the columns used in the join clause and in
the where clause to fecilitate the faster fetch.
