- I would be very skeptical of any Oracle benchmark claims because Oracle's
- license prevents the publication of any benchmark results without Oracle's
- permission. Therefore, the only Oracle benchmark results you will see are
- the "good" ones.

- As far as I know, no one has yet integrated content-based retrieval (CBR)
- with BLOBs and large text fields, which is what you really want. Remember,
- though, that BLOBs are relatively new and I would expect that something like
- this will start happening in the next year or so.
-
- It might be interesting to the vendors who are reading this group if we
- were to start a thread on what a CBR-BLOB capability would look like. The
- way I conceive it, at its simplest, it would involve a new type of index
- ("create text index"?) which would set up a varchar or BLOB column to be
- retrieved via CBR operators, along with some new CBR operators (at least
- contains, and probably more sophisticated stuff than that.)
