The best part in my experience was direct SQL integration int COBOL programs. I had prior SQL experience when I started writing COBOL programs I didn't face any difficulty whatsoever. Moreover there are regular upgrades which we handle, which adds to the...
When partitioning a table space, difficulty arises in updating indexes. You must delete a row and insert it with new values. Key values must be known and defined ahead of time as once they are committed, you can not roll them back. DB2's language is not as...
I like standards-compliance of PostgreSQL best. As we know, PostgreSQL follows the majority of the SQL2011 standard, is ACID-compliant and transactional using multiversion concurrency control (MVCC); has updateable views and materialized views, triggers,...
Replication, at least in 2006-2007 was slony and log-shipping. Slony would fail to create new replicas after about 100 gigs on somewhat serious enterprise hardware due to it recreating the database via a pg_dump method which obviously stops working after...
