I do not know your background, congratulations if you
were able to develop performant mappings. But it's not
the case on most clients I've seen where average
developper were developping with the ETL tool.
I'm sure that an experienced DBA with a good knowledge
of its working environnement and who has always
performance, ease of maintenance and robustness in his
mind, could develop good mappings.
In the real life, the development is done by people
with a medium knowledge of SQL, a weak knowledge of
tuning and the rdbms and with 3-4 years of experience.
