Of course...and relational databases might not be the right tool for the right job. Making a blanket statement that there is a "default" for data in a web site

Of course...and relational databases might not be the right tool for the right job. Making a blanket statement that there is a "default" for data in a web site is purely ignorance of the problem (i'm not saying you're saying that....) Of course the original author seems to think that most relational databases lack performance and / or features. There is no one size fits all situation. This is why companies like facebook, netflix, etc. use combinations of relational databases and nosql databases (although i think netflix is almost completely over to simpleDb now...)
