To prefix, or not to prefix.  That question comes up alot.

I vote against prefixing in the database itself.

Makes querying the database cross reference files much easier.
select system_table_schema, system_table_name, system_column_name
from qsys2/syscolumns
where system_column_name='LOCATION'
order by 1, 2, 3
SYSTEM_TABLE_SCHEMA  SYSTEM_TABLE_NAME  SYSTEM_COLUMN_NAME
    ADTSLAB             PARTORDER           LOCATION
    ATSDLSSQL           SYSPACKAGE          LOCATION
    DHTBRAF             DUNDST              LOCATION
    DHTDIVF             DUNDST              LOCATION
    DHTIREF             DUNDST              LOCATION
    EDI.GDI             DUNDST              LOCATION

When you are joining multiple files then you don't have to remember
cmcust=clcust

Invariably someone forgets to prefix a field anyway, even in vendor
supplied software.

And, while the drop may be useful for those of us forced into using files
with prefixed fields, those who will use it might not be inclined to
prefix their fields in the first place.
