Oracle Rdb Statement of Direction
http://www.oracle.com/technology/products/rdb/htdocs/rdb7/rdb_statement_of_direction.html

The above shows there is plenty of collateral stating Oracle's
commitment to Rdb. I would say it is also partly due the continual
industry-leading innovation of its development team and quick new
feature release cycle despite having 3 development trees (7.0, 7.1 and
7.2). The Oracle Classic team has over 90 platforms to contend with
providing (in many aspects) a lowest-common denominator functionality
(Oracle Classic integration of the DLM on OpenVMS is an example where
this has not been the case). But Oracle Classic has a completely
different DB engine model, and has not yet been able incorporate (or
make as good use of) many of the features and advantages developed
originally and often exclusively for Rdb. Some features were mostly
unnoticed by the public for many years before they became buzzwords for
competing products.

     - Snapshot coordination of serialized transaction data
     - Cost-Based Optimization
     - precompiled optimized queries
     - optimizer hints
     - BLOBs (segmented strings) since 1984 (became buzzword c.a. 1990)
     - bit-mapped indices
     - latches (ultra-efficient locking)
     - BLASTs used for efficient SW-interrupt-based resource coordination
     - pseudo-ranked indices
     - transaction- and quiet point-aware on line backup utility
     - true fully-shared clustering and DLM integration
     - cluster-aware rollback resolution
     - true default "serializable read transaction isolation" without
       needing an additional TP Monitor front-end, despite and a
       necessary consequence of Rdb's ultra-scalable direct per-process
       DB access model (compare Oracle Classic's served data
       resource bubble model).
     - log-based (AIJ) ultra-low transaction overhead Hot-Standby
       database capability
     - log-mining (AIJ) transaction replication interface

      and more...

Rdb has also always been at the forefront of implementing SQL standards,
going far beyond the basic "Entry-Level" SQL Standards Compliance of
almost all other SQL products.

Cheers!
