Itschak, I started in the COBOL arena, I briefly programmed in Natural/ADABAS for the SA Revenue back in the 80's and touched on DB2 when I managed 3 DB2 training systems for IBM SA back in 96-98. They were DB2 of course.
My thinking is this... Natural is very easy to program, but very expensive to run in terms of CPU usage, at least it was back then, compared to the pre-Natural code... When I look at DB2, you can have it running very efficiently by doing proper systems analysis and by preventing expensive SQL statements. In my experience it is the incorrect use of SQL combined with the fear if more indexes(mainly because it costs disk space), that would ultimately make any one of them less efficient. The reason why both(DB2/Adabas) are still with us is probably because they ultimately offer a different set of benefits to their users.
