The BI developer is the person who works with business intelligence technologies, in the case of SQL Server, like Reporting Services, Analysis Services, and Integration Services.
If you’ve read some job descriptions for database developer jobs, you might have some idea. They might all be essential requirements but, really, if that’s all your DBAs are doing, you’re probably paying them too much and wasting their talents. If a Production database is down it’s obvious that recovery time is crucial. However, whilst we have a strong appreciation for those time-scales, we can overlook the fact that Project Teams are often working to very tight deadlines too, dictated by a business need for an application to go live.
These days, especially for websites, databases often need to be available constantly. Managing very large databases involves expertise in managing operations that are potentially time-consuming, such as table copying. The database admin needs to understand techniques like table partitioning (Oracle), federated databases (SQL Server) or replication (MySQL) to enable a database to scale to large sizes while still being manageable. A DBA is a technician skilled in SQL and very large databases who is responsible for managing database software, backup and recovery processes, data security, and storage and capacity planning.

DBAs also work with users and developers to provide access and guidance on database issues.

Database administrators are responsible for developing, implementing and periodically testing a backup and recovery plan for the databases they manage. The DBA then installs the database software and selects from various options in the product to configure it for the purpose it is being deployed. As new releases and patches are developed, it’s the DBA’s job to decide which are appropriate and to install them. And if the server is a replacement for an existing one, it’s the DBA’s job to migrate the data from the old server to the new one.
If I’m to be held responsible for the non-operation of a database (and I will be) then I should have the implicit right to stop anyone from doing anything that will compromise its operation. However, having a say in related matters is not the same as having complete ownership. A development database is there for developers to use, not to keep me in a job and let me practice my DBA skills. The database belongs to the developers and I’m just taking care of it for them. We are not database guardians, who must be obeyed, but should be there to help and advise.
