Hi All

I am designing DB2 database. I have some entities each has nearly 40-60
attributes. Each of these entity (table) have password, some other
information as high security attribute. So should i create new entity
which hold password data for all entity or should I place password data
in respective entity.In each case i will encrypt password.
in both cases what will be effect with respect to performance and
security.
Each entity (table) have more than 10 million records.


Thanks and regards
Suresh
