The purpose of this question is to determine what type of database administration work you do or are capable of doing. As a DBA, you may have performed to jobs described by both of these titles. However, when answering this question, you should identify the title listed in the job posting. The exception to this would be if the job posting indicated that you would be doing tasks related to both of these different titles.

William Swansen

"Since the job posting I responded to was for a development database administrator, that is the role I would like to perform. However, in my previous positions, I have functioned as a production DBA, so I'm capable of doing both of these jobs. Having a strong background in development helps me in my production role when managing a database. Conversely, since I have experience administrating production databases, I know how to design a database to optimize its performance and ease of use."
