Do you feel like DBA/DBD Is a "secure Field" still?
Yes, absolutely. Whether you use NoSQL (which means "not only SQL" not "no SQL") or an enterprise RDBMS, there is still quite a large need for architecture, data modeling, design, tuning, data security, etc. If you think throwing your databases on SQL Azure means you no longer need a DBA and it just runs itself, you might be in for a shock. Every company uses data in one way or another, and the trend I see developing is that more and more companies are moving to taking their data to big solutions. I don't anticipate the need for the DBA/DBD folks around that to dwindle, though I do sense that the nitty-gritty specifics involved in any such role are constantly evolving.
