Hi,

..so all the rows whose department number are 100 will store in one page |
I have gone thru link provided, is any kind of Index enforces the DB2 how to store the data internally in the table space? OR INDEX used to increase the performance of DML(SELECT/DELETE/INSERT)?
I believe Index will have only key value (by Index defination) along with pointer to access the data from table.
Correct me if I'm wrong. |

Correct ... Index has nothing to do with how actual data is stored ... |

Hi,
I really don't know what sort of examples were discussed in the previous link regarding cluster Index. |
