Using indexes on DB2 for i5/OS to improve performance

How can I access a sequential file faster with the help of index? Can we use a SELECT statement with index clause to achieve this?

Yes, indexes can help the performance of some SELECT statements, provided you have the proper indexes in place for the query optimizer to use.

To get a better understanding of how DB2 for i5/OS can utilize indexes to improve performance, I'd strongly recommending reading the Indexing & Statistics Strategy white paper online.
