what is alternate index?
Answer / bhakti
It is used whenever data needs to be retrieved on the basis
of the other fields i.e. other than primary fields.
Supported by KSDS and ESDS only but not by RRDS and LDS
because they do not have any index component.
Not more than 253 AIX (Alternate Index) can be specified.
AIX is composed of Primary key record along with the field
identified as secondary key.
