not sure if this question rely belongs here but what sort of training would someone need to become a SQL Server DBA? Going for a job as a junior DBA which includes training so just wondering what that might include?
Here you go. I'd say that a Junior DBA ought to have the knowledge required to become certified MCTS on SQL Server, probably Exam 70-432 for a general DBA. Assuming that you mean MS SQL Server, and not some other SQL Server.
take a look at the articles and blogs on http://sqlskills.com/ These are the real world things a DBA needs to be concerned with. It probably wouldn't hurt to have a thorough understanding of different RAID levels
The best answer a DBA can often give when asked a question is, "it depends."
