I've often been asked to attend meetings as the database\technical contact.
The audience is usually the business managers with low or very little experience with databases, hardware and all the other fun stuff we like to get involved in.
In my experience, the ability communicate at a technical level appropriate to the audience is very important. Know your audience and their abilities, communicate with respect as they usually will be contributing to your salary.
