Quite some time ago, I read a fascinating article, co-written by easily the best Oracle instructor I ever had the pleasure of being taught by in Joel Goodman, which talked about the skills required to be a “DBA 2.0”.
They even mentioned Exadata needing its own “version”, though they suggested it would be “DBA 2.1”. I’m not sure Exadata had made it out into the wild at this point.
The article was written five or six years ago and was tremendously prescient. With the data industry at such a fascinating crossroads with Big Data, engineered systems and extreme performance, how will the DBA role change to keep up with the demands of the ever-increasing volume and mission-critical exploitation (hopefully the beneficial kind) of enterprise data?

It Was Like That When I Got Here
