Should a DBA support the concept of application design based

Should a DBA support the concept of application design based on thorough knowledge of the database. Is that part of DBA\'s job?

Solution

Application DBA focuses on database design and the ongoing support and administration of databases for a specific application or subset of applications. The application DBA is likely to be an expert at writing and debugging complex SQL and understands the best ways to incorporate database requests into application programs. The application DBA must also be capable of performing database change management, performance tuning, and most of the other roles of the DBA.

That being said A DBA is not supposed to support whole of application design as that is the work of application design architect.
