In terms of job responsibilities and activities, what is the difference between a Database Administrator (DBA) and a Database Architect?
I would say the term Database Administrator covers the full gamut of database duties: design, development, production support, performance tuning, report writing, OLAP, etc.
A Database Architect is involved in the design and development of large or complicated database solutions. However, the Architect is usually not involved in the day-to-day operations of the system once it is deployed.
I don't really like either term. Database Administrator is too vague, Database Architect sounds pretentious.
I am a computer programmer at heart, but aren't we all?

The DBA does just what the name suggests...administrator of the database. Based on the specific RDBMS being managed, the role DBA involves implementing the following aspects:
DATA ARCHITECT (DA)

Except in the most formal of companies, specific titles are largely meaningless and DBA can mean nearly anything. Some DBAs are operationally focused, some are development focused, some are analytics focused. In reality, except in very large enterprises where titles are strictly controlled and people have siloed jobs, most DBAs will cross several areas of the company. In any given day, I interact with operations, development, and analytical areas of database administration.
Ultimately, the job of a DB Administrator/Architect/Engineer is to be a subject matter expert on the database and to assist the business in best utilizing that resource.
