I think it's true to say "it depends".
In addition to the points made above, important factors are whether there
is a separate development and production support team and whether the
operation is 16x7, 24x7. For example, two DBAs might be a viable team for
an 8x5 operation, but for 24x7 you might need a minimum of six in three
shifts...
I don't think there's any magic "right answer". The amount of work created
for DBAs by developers also depends on the developers level of experience
of the database, whether you're using "SmartDB" techniques, etc... It
depends.

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.

Those numbers are based off of the developers who are tied to 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?
Jeff
