If you want to specialize in javascript and html that's fine. The middle/backend/API then ought to be developed by someone knowledgeable in SQL - but it's still a developer, not a DBA. DBAs are sysadmins not programmers. If you want to specialize in middle/backend development and think you should be able to defer all your SQL problems to a DBA then no your dead wrong. You simply cannot be a good backend developer for web applications utilizing RDBMSs and not know this shit.
