Googling out for definition and explanation for sixth normal form only resulted in the following information - "6th normal form states that a relation R should not contain any non-trivial join dependencies". Also everywhere it is stated that this normal form takes into account the temporal (time) dimension to the relational model, and that current implementations like SQL server 2005 do not implement this normal form.

Any more explanation and preferably an example would help in understanding the concept behind this normal form. Received on Mon Jul 30 2007 - 12:45:00 CEST
