A Sample DBA Job Posting

The job of a Database Administrator, or DBA, is constantly changing and adapting to the technologies used to manage data in modern organizations. With that in mind, I decided to put together a sample DBA job posting incorporating as many regular DBA duties as I could think of.

Take some time to read through this posting and let me know what you think. Is this the way you view the role of DBA today? Is this what DBAs do at your site? Is there anything significant missing? Is this too much work for a single individual job? Would you apply for this job? Respond with comments please!
