What is interesting in my place of employment is that the Database Technologies department is broken up into three sections:
Systems DBA : Primarily responsible for Installing SQL Server, Creating Logins, monitoring performance in environments outside of development.
Production DBA: Primarly responsible for deploying scripts to the production databases.
Development DBA: Primarily responsible for database creation, script creation, physical designs and coding standards.
I come from a programming background and am now a development DBA. With that separation I was, and to some extent still am, worried that I might loose some of the skills that the Systems DBA handle. Some of the things that I would be responsible for in a smaller shop. Not sure but the article looks focused on being a complete DBA in a small to medium shop setting.
