A lot of the database questions have specific database engine tags on them. I think we should stick to the database engine tags instead of the generic database.
I think that we should burn the database tag and ask the user to use the specific database engine tag (sql, nosql, mysql, etc.)
I just don't think that adding a database adds anything to the question. It may only exist for SEO, and if that is the case I think we should set some guidelines on how to use it properly because we definitely need to know the specific engine being used in the code.
