We have both on-site development and third party applications on our site. Therefore, it's somewhat difficult to extract the "developers per dba" metric.

But I can give you the "number of databases/dba" instead: my team consisting of 6.5 full time employees is responsible for 200 Oracle and 500 MS SQL Server databases including a couple of Reporting and Analysis Services instances.

I think you've already identified a part of the solution ("We are working on getting the developers to be less depended").

That being said, we've automated almost all recurring tasks, such as database creation, snapshot/rollback, upgrade/patching, cloning, Oracle software installation etc. On top of that we built a self-service interface for the application people, so that they don't need us for tasks like fallback, cloning, database upgrades and so on. By doing so, not only did we massively improve agility, scalability and overall customer satisfaction, but also our jobs became much more fulfilling by replacing toxic repetitive toil with more challenging tasks.

Good luck!

For your own projects you need to work with your project managers to get your projects on the table too. Items to maintain, monitor, upgrade systems are just as important as some of the development work.

Thank for your input. We keep up with their needs (for the most part) but our own projects lag behind big time. We are working on getting the developers to be less depended but there is always things and we like being in the know of what is going on.

The numbers are much higher when you look at all developers on the teams you may support who do no development against a database.

As you said it really depends.
In the consulting world for contracts I have seen 4 to 1, when calculating DBA to Developers. In the commercial world I have seen upwards of 75 developers to 1 DBA. And a low of about 6 Developers to 1 DBA. Really depends on how much help the Developers need or how much control of them you need. Can you keep up with the project time lines based on your ratio and their/your needs.

I know this is not an exact science and every company is different and a lot of factors goes into this. But just curious how many DBA's you have compared to how many developers? We do mostly custom development of many applications for the company. We have 20 developers that do .Net, Web, Cobol, VB, and just starting APEX. They all also do their own PL/SQL, which we review. There is 2 of us as DBA's who also do development. We support 5 Oracle databases and a bunch of MSQL databases but those are all third party systems.

Is there a common or magic number?
