I believe that if you walk into any business or IT shop in the world, you will likely find a database system that is build on the Relational Theories of E. F. Codd.  I would also guess that most if not all of these databases are also built on Tables with Rows of data.  This has long been accepted as the method of storing large amounts of data without the inherent problems of using flat-files, the method used previously.

A little while ago there was a car commercial that had the motto, Shift Happens.  It was implying that the company had made changes in the way they designed their newest cars.  I took it to mean that things change, no matter how much something is established.
