Different names for the same thing. Snapshots is being phased out and the
new terminology is materialized views.

Please
respond to
ORACLE-L
Hello All,
Sun 5.8 Oracle 8.1.7.2
At a client site the developers are building an application that runs
against several data-marts. The marts have tables with many 16+ million
record tables. I have explained to them that read-only materialized
views would help speed up some of their queries.
The local developers are pushing the use of snapshots, I would like to
use materialized views. I do not have much experience with either one. I
have been unable to find a good comparison of snapshots vs. materialized
views. When should one be used over the other? What are the
dvantages/disadvantages of either one in this situation? I know that
query rewrite only works with MVs, but that isn't a factor in this
situation.
Thank you for any information you can provide.
