Thank You. Good idea for table types. that is something what we should
decide before create table.
Example: use varchar2 not varchar/use number when business need number....
Perhaps, We should know about data... On new 11G, Compression is good for
DW. How do you think?
On 11gR2, Database Smart Flash Cache, this may good for OLTP. If we talk
about Exadata, we will use "Exadata Smart Flash Cache"
and your idea?
Thank You
