Could any one tell me, how the index  works in cache db, Consider for example, I have a table called "Employee" and the fields as "EMPID, EMPNAME, EMPAGE" and I am having index for EMPID as IDX_EMPID and trying to get the record using the following query as

SELECT * FROM EMPLOYEE WHERE EMPID="005"

and the table data be like

EMPID EMPNAME EMPAGE

001       ABC            20

002       AAA            21

003       ABB            23

004       BBB           20

005       BDF           24

006        EEE          22

When I was searching for the ideas to migrate IRIS DB to Oracle, I could find a tool called "ESF Data Migration tools" over internet with easy steps.

Can we use them to migrate?
