The archival viability of CD and DVD is sometimes discussed on a video
editing forum I participate on (dvdoctor).
My understanding is that the best CD-Rs will now theoretically last
longer than a pressed CD (presuming that they are cared for well).
However DVD-Rs (or DVD+Rs) haven't yet even come close to exhibiting the
longevity of pressed DVDs.
It is my understanding that one of the design goals of Blu-ray was more
resilience for the data recorded on a disk, however as this is a
relatively new technology, and while the data on the disks may be more
resilient, there were certainly indicators that blu-ray disks are more
brittle than DVDs and CDs.
Finally, be cautious with regards the Archival Gold DVDs. From reports I
have read, it appears that while the gold layer may be inert and this
may help the longevity of the disk, the manufacturing quality is so
poor, that this may end up not being the high quality media it purports
to be.
Thus if you do really care about your data, then hard disk or tape are
probably the way to go in spite of the possible inconvenience of format
migrations every few yeas to ensure the availability of the data as
technology changes.

Uwe,
Assuming you'll be using Oracle in ten years and Oracle keeps its
promise, export is probably a good bet. But here's an interesting,
"simple" alternative. At regular intervals, extract the app and
dictionary table data to text files, extract the code to text files,
keep a printed data model, and archive it all to disk, CD, DVD, etc. -
some type of storage that has a good chance of being around in ten
years. This allows you to read the data and be able to determine how
the app handles it without actually having the app and database running.
And it would work for non-Oracle databases and apps. It's a simple
concept, but not a new one. And no, we haven't implemented it. We've
been using export - for now.
