Different types of Descriptors??

Hi all,

Can anyone tell me the difference between these -->

descriptor???

Thanks,
Rahul

A descriptor in general is a key field for which an index structure (inverted list) will be built by Adabas.

For a description of the various “special” descriptors please read
