IBM ADABAS Interview Question:
What is the difference between Null compression and default compression?
Submitted by: AdministratorThe default compression type for ADABAS is 'Normal'
compression. This compresses the data by removing trailing
spaces from alphanumeric fields, removing leading zeros and
packing numeric fields, and leaving packed fields as is.
Null Suppression is a type of compression. The field must
be designated with 'NU' for this compression to occur.
Null suppressed fields that are blank or zero only take up
one byte insted of two. If there are multiple empty fields
together they can be compressed into a one byte empty field
count.
