What was the first database you used back in the day? DB2 though I was not a full time DBA. I managed the operational systems and security side of things and worked with the DBA's quite extensively. After that was mostly Oracle and mostly dealing with testing backups, managing disaster recovery procedures and of course make it go faster. Looking back, there were so many other options that I missed I don't think you really missed anything good. Modern open source databases drew from many lessons learned from the previous databases and in my opinion are much simpler, faster and pragmatic. Some of the more complex features of some of the older databases have since moved into the application stack.
