I like this link.
I like it because academic developers whom are keen on CV polishing are convinced the RDBMS is old news. If it's not an ORM model or even better a NoSQL implementation like Cassandra or MongoDB then it's old hat.
Yes, they can scale immensely which is fantastic but they are not suitable everywhere, Those implementations don't lend themselves to structure, to referential integrity and the beauty of having one master version of a data set.
I'll let the title speak for itself ...
Relational Databases Aren't Dead. Heck, They're Not Even Sleeping
