what is the difference between Null compression and default
compression?

Answer Posted / robert gosling

Default compression deletes trailing blanks in alphanumeric
fields and leading zeros in numeric fields.

Null suppression (NU) differs from default compression in
that searches, on descriptor fields defined with null
suppression, do not return records in which the descriptor
field is empty.
