Kevin, Folks
We are also facing a similar issue with our "Banking" Application
product where approx 1/3rd of the Database size is taken up by 1 Table
which stores the Customer Signatures in one of its LONG/LOB fields.
Database Sizes are in the range of a few Tera Bytes.
The Banking Product is a primarily Pro C Application, with java
functions too.
Qs IN OUR BANKING PRODUCT CASE, THE RESPECTIVE SIGNATURE IS VERIFIED AS
PART OF AN OLTP TRANSACTION BY A BANK STAFF USER & THEREAFTER A
CREDIT/DEBIT OLTP TRANSACTION IS PASSED TO THE RESPECTIVE CUSTOMER'S
BANK ACCOUNT. DOES THIS QUALIFY FOR STORAGE AS EXTERNAL DATA?
SOME ADDITIONAL QUESTIONS ARE EMBEDDED BELOW IN CAPITALS.
Thanks indeed

I'll take a stab. Historically, there have not ben options for getting
multiple servers access to unstructured data (read CFS). So
at least with OPS and RAC, stuffing these, actually quite-unstructured,
pieces of data into the database at least got them accessible to
multiple nodes. Also, historically, there were no PL/SQL callouts
to get unstructured data.
These 2 factors are now historical. You can deal with external data
nicely with 9i and moreover 10g and
CFS and NAS technology is not spooky anymore (well, I think it might be
to the open source folks).
* ANY SAMPLE LINKS, DOCS ON EXTERNAL DATA ACCESS?
* IS EXTERNAL DATA ACCESS SLOWER VERSUS WHEN STORED WITHIN?
The other force was the desire in the mid 90s for Sybase,Informix and
Oracle to be *the* repository for all data...there were musings
of OODB and RODB and all those things that never really got anywhere.
That is, Informix and Oracle wanted to be media servers in addition to
databases and that was at a point in history that predated the
web, really.
There are a lot of Oracle sites that blend the best of what Oracle
does and the best of what Oracle does to support external unstructured
data.

Gannett Media comes to mind.
