DBA Role

I recently read an article by Scott Ambler called “Where did all the positions go?” It was about how traditional software roles fit into an agile development paradigm. I thought I'd make some observations as to how I think this relates to our organization's current state of database development.

One thing I've noticed since we have adopted the agile development model is that I've been doing a lot less DBA work. Sure, I still do some modeling, write some SQL, and put the occasional database together but that is what I would consider database development; definitely not administration. I have often felt that, as a DBA, I'm not able to make a full contribution to my agile team.

Another thing I've heard from some of my database peers is that the iterations tend to be front loaded with database work because much of the development is dependent upon the completion of the database portion. Once the database work is done, development of the application can continue and the database developer tends to settle down to an application support role with minor fixes. Unless your project is a database only project, there is not typically enough database work to fill multiple complete iterations.

Scott's original positions question, as it pertains to our group, might be asked as “How does a traditional DBA fit on an agile development team?” The short answer is “s/he doesn't.” Does this sound harsh? Let's take a look at the longer answer.

Although the traditional DBA doesn't have a fully contributing role on an agile team (neither does the traditional programmer, business analyst, or project leader for that matter), Scott refers to something he calls a “generalizing specialist.” As traditional database developers, we obviously cover the “specialist” portion of this role but, with just the specialist portion covered, we are still only partial contributors to the project team.

To become fully contributing members of our agile teams, we are learning to expand our contributions to some non-database areas as project needs dictate. We are developing the “generalizing” to go with our “specialist.” I've seen some of our formerly traditional DBAs doing things such as writing VB.NET code, running regression tests, working with VB and C# CodeSmith templates, and creating and executing QTP scripts. These are definitely skills you don't expect to develop in a traditional DBA role!

So... about my previous lack of contribution as a DBA; job title aside, I'm now fully contributing to my team as a general agile developer with a database specialty.
