Not sure I agree with prior statements. The Production DBA is the single person(s) responsible for the livelihood and availability of production database environments. He/She/It is the first line of contact should a database-centric application either not perform to expectations or crash. The Production DBA is responsible for environment tuning/performance/optimization, disaster recovery, backup/recovery, security, generic administration, etc. They are also responsible for enforcing production standards for all application development teams and ensuring that all is smooth. In many cases the Production DBA has the same responsibilities for the development environment to ensure that all guidelines are followed as software is transitioned from Development to test to validation and finally production.
The Application DBA is responsible for the overall integrity of a specific application. They are responsible for the physical implementation of the logical data model for that application, application-specific performance issues, application-specific security issues, etc. Note the theme: application specific. This could include any application, even Oracle eBusiness Suite. Application DBAs are DBAs!!! However, many are just starting out in the field so this position was created by many organizations to let them get their feet wet. The primary difference between the two. One absolutely needs a pager and doesn't sleep. The other does. Thank You Stephen P.
